Beckham underwent surgery Monday night on his fractured ankle.
Harris is expected to undergo surgery Tuesday as well.
Marshall signed a two-year, $11 million deal with the Giants in the offseason. He had 18 catches for 154 yards and no touchdowns in five games.
Marshall was injured when he attempted to make a catch deep down the left sideline and landed awkwardly. Before leaving, Marshall had two catches for 15 yards during the second-quarter drive when receiver Sterling Shepard (ankle) was injured.
The Giants had said Shepard was undergoing tests Monday to determine the extent of the injury.
Marshall, who was in his 12th season, is a five-time Pro Bowl receiver who has played with the Broncos, Dolphins, Bears, Jets and Giants.
There were high hopes after Marshall signed as a free agent this offseason, but he wasn't able to get comfortable in the offense and in a new setting.
Marshall was slowed this summer by a shoulder injury, and he didn't develop a rhythm with starting quarterback Eli Manning
RENTON, Wash. -- Seattle Seahawks left guard Luke Joeckel is scheduled to have an arthroscopic procedure on his knee this week and will likely miss the team's next game, according to coach Pete Carroll.
After their bye this week, the Seahawks play the New York Giants on Oct. 22. Asked if Joeckel has a chance to return for that game, Carroll said Monday: "I think that's going to be hard to count on that. That's probably too much to count on."
Joeckel has not missed a snap while starting all five of Seattle's games this season, but he's been dealing with lingering effects of the major knee injury he suffered last season. Joeckel tore his ACL, MCL and meniscus last October, cutting short his final season with the Jacksonville Jaguars, who made him the No. 2 overall pick in 2013.
The Seahawks signed Joeckel to a one-year deal in free agency. He was limited over the offseason while recovering from his knee injury and was among several players who briefly left the team in late August to receive Regenokine blood treatment. Joeckel has routinely been given days off from practice since the regular season began.
"We brought him back very carefully, and there was something that was kind of hanging in there that was irritating him for some time. And we tried to wait it out and see what it was, and we have waited as long as we can wait and he's been a stud about it," Carroll said. "Now it's time to get it cleaned up, and hopefully it'll be really smooth for him and the docs will get in there and get him cleaned out, and away we go."
The Steelers officially announced the dismissal of two coaches today, confirming the removal of offensive line coach Larry Zierlein and announcing the departure of special teams coordinator Bob Ligashesky.
Both were original hires of Head Coach Mike Tomlin in 2007.
Offensive coordinator Bruce Arians will be retained. It's clear that despite his firing being a done deal early in the week in the minds of several in the organization, those who wanted Arians to stay did enough convincing that the team has decided to keep him around for one more season.
Ligashesky, a McKees Rock native, came to the team after NFL stints in Jacksonville and St. Louis. In the Super Bowl winning season of 2008, Ligashesky's coverage teams ranked 1st and 4th in the league, respectively, covering kickoffs and punts.
This year, however, the team's coverage units dipped to among the worst in the league, 23rd and 27th respectively in return average against (including allowing a record NFL four kickoff returns for scores).
The development of return man Stefan Logan was not enough to save Ligashesky's job, with Logan finishing the year 8th best in kick return average.
The team also announced today nine players were signed to their offseason roster:
TE Eugene Bright, WR Jason Chery, S Tuff Harris, DT Steve McClendon, RB Isaac Redman, RB Justin Vincent, CB Trae Williams, DT Scott Paxson and K Piotr Czech.
Hart injured his ankle last week against the Dallas Cowboys. He finished the contest, but missed Thursday's practice.
The second-year tackle limped off after the second play against the Lions. He will not return.
The Giants moved left guard Justin Pugh to right tackle in Hart's absence. He practiced at that spot throughout the week. Pugh played right tackle for most of his first three professional seasons.
Brett Jones entered the lineup at left guard with Pugh moving to the outside.
In the third quarter, Giants linebacker J.T. Thomas was ruled out with a groin injury.
GREEN BAY, Wis. -- Randall Cobb, Jordy Nelson and Mike Daniels all appear to have avoided season-ending injuries after dropping out of Sunday night's loss at the Atlanta Falcons, but all three Green Bay Packers playmakers likely will need all week to determine whether they can play against the Cincinnati Bengals.
Coach Mike McCarthy refused to give any injury details on specific players during a news conference Monday night.
"I don't have anything for you on any of the players," McCarthy said. "We're still working through it. We got back at 3 a.m., so we had a lot of work to do."
However, a source told ESPN's Adam Schefter that Nelson's quad strain is not considered serious. He is is "50-50" for Sunday's game against the Bengals, the source said.
When asked whether he was concerned any of the injuries were season-ending, McCarthy said: "I don't think I'll be reporting on season-ending injuries, no."
Nelson left during the Packers' first drive because of a quad injury to his right leg and did not re-enter the game despite going through treatment and riding an exercise bike on the sideline. It's the same leg that Nelson hurt in the 2015 preseason, when he tore his ACL and missed the entire season. This, however, is a soft-tissue injury.
So is Daniels' ailment. The defensive tackle pulled his hamstring in the first quarter and also could not return.
ATLANTA -- Two of the Green Bay Packers' biggest playmakers didn't it make through the first series of Sunday night's 34-23 loss to the Atlanta Falcons. Another tried to gut out an injury but finally succumbed.
Receiver Jordy Nelson hobbled off the field after eight offensive plays because of a quad injury, and defensive tackle Mike Daniels pulled a hamstring on the Falcons' first drive. Receiver Randall Cobb tried to play through a shoulder injury and finally dropped out in the fourth quarter.
"I got hit in the first quarter and then aggravated it," said Cobb, who was the only one of the three that was available to discuss his injury. "I think I'll be all right, though."
For Nelson, it was a non-contact injury to the same leg in which he tore his ACL in the 2015 preseason and missed that entire year.
Nelson tried to work through it on the sideline. After undergoing treatment, he rode a stationary bike and then jogged on the sideline but never returned and was ruled out of the game shortly after halftime with the Packers' trailing 24-7 at the break.
Nelson did not have a ball thrown his way before he left with the injury. He caught seven passes for 79 yards, including a 32-yard touchdown in the season-opening win over the Seahawks.
Daniels' first-half hamstring injury came after he played perhaps the best game of his career in the last week's season opener against Seattle. He had 1.5 sacks, four quarterback hits and seven tackles.
The Packers also lost two members of their secondary during the game, cornerback Davon House
The Redskins had planned to increase the snaps for second-year WR Josh Doctson in Week 2, but hamstring tightness has scuttled that plan.
WR Markus Wheaton is listed as questionable for Sunday after being limited in practice all week from recent surgery to repain his left pinkie.
MINNEAPOLIS -- New Orleans Saints right tackle Zach Strief was ruled out of Monday night's game against the Minnesota Vikings with a knee injury after he walked off the field with trainers before halftime.
Losing Strief is a big blow to a Saints offense that was already starting the year without left tackle Terron Armstead because of a shoulder injury.
New Orleans' offense struggled to generate much of anything in the first three quarters, falling behind 19-9 with 196 total net yards.
Redskins WR Jamison Crowder (hip) seemed surprised when told he was listed as questionable for Sunday; he says he's ready to go.
Jordan Reed says the toe injury that has kept him out felt good during Wednesday's practice, and he's eager to test himself in preseason action.
"I'm really broken-hearted about George Fant getting hurt," Seahawks coach Pete Carroll said. "Just unfortunate. He's done so much and come so far."
Fant suffered the injury with 8 minutes, 49 seconds left in the second quarter. He was moving backward in pass protection when teammate Justin Britt, who was on the ground, rolled into him. Fant immediately went to the ground and clutched the knee. Trainers tended to him for several minutes before carting Fant off the field.
Fant started 10 games at left tackle last year and was going to start there again in 2017.
Carroll said earlier this summer that Fant had the best offseason of any Seahawks player. Fant bulked up from 296 pounds to 320 pounds.
Versatile defensive lineman BIlly Winn, who would have been in a tight battle for a roster spot, got the news he feared on Friday -- a torn ACL.
Rookie Marshon Lattimore sat out Wednesday because of what Sean Payton called a knee "tweak," and fellow CB Delvin Breaux also missed practice.
