From an OSU Athletic Department press release on Saturday:

COLUMBUS, Ohio– Jordan Hall, the senior running back who figures to be a key go-to player in coach Urban Meyer’s offensive attack this fall, will be out of commission for approximately 10 weeks while recovering from surgery Friday to an injured foot.

Hall, who enters his senior season with 2,513 all-purpose yards to rank 26th all-time at Ohio State, suffered an accidental cut to the bottom of his right foot Wednesday afternoon while walking in grass outside his residence in Columbus. He had surgery Friday at the Ohio State University Medical Center.

“This is an unfortunate accident to a really fine young man,” Meyer said. “He’s handling things well, though. He’ll be in a non-weight bearing cast for about six weeks and then he’ll rehabilitate the injury for at least four weeks after that.”

Ohio State opens its fall camp in about five weeks – the first week of August – with the first game of the 2012 season set for Sept. 1 against Miami of Ohio.

Hall has 817 career rushing yards with five touchdowns and has also caught 21 passes out of the backfield for 202 yards and four more TDs. He came out of spring drills No. 1 on the depth chart at running back. Junior Carlos Hyde (707 career rushing yards and six touchdowns), sophomore Rod Smith (116 and one, respectively) and true freshman Bri’onte  Dunn were also competing in the mix at running back throughout spring.
