Wesson, a sophomore who is averaging 14.6 points and 6.7 rebounds per game, will return this season, according to a school release.
He had his third double-double of the season in the Buckeyes' 90-70 win over Iowa on Tuesday, finishing with 18 points, 11 rebounds, 4 assists and 3 blocks.
Ohio State (18-10, 8-9 Big Ten) is a No. 9 seed in the latest Bracketology projections by ESPN's Joe Lunardi, but the Buckeyes likely need another win or two to feel safe on Selection Sunday. They travel to No. 14 Purdue on Saturday, face Northwestern next Wednesday and finish at home vs. No. 19 Wisconsin before the Big Ten tournament.
With a lack of size behind Wesson, expect Holtmann to rely heavily on sophomore forward Kyle Young down low. Young is averaging 6.5 points and 4.4 rebounds off the bench this season.
