Duffey can transfer without penalty after graduating from Texas Tech.
This fall, he led the team with 2,840 passing yards and 18 touchdowns with only five interceptions, and he completed 65.1 percent of his passes. The 6-foot-1, 200-pound redshirt junior from Mansfield, Texas, also rushed for 212 yards and a touchdown for the Red Raiders (4-8).
In 2018, Duffey led Texas Tech with 369 rushing yards and four touchdowns on 79 carries. But he opened the 2019 season behind starter Alan Bowman, who suffered a shoulder injury in September and opted to redshirt.
