CLEMSON: Former starting offensive lineman Barry Humphries has decided to leave the Tigers.
Clemson coach Dabo Swinney announced the move Friday. Humphries, a senior, was listed as a fourth-team guard heading into fall camp and was schedule to serve a two-game suspension for violating team rules.
Humphries said in a statement that he was not going to get a lot of action in camp because of his suspension and it would be difficult to regain a starting spot. So he wanted to transfer somewhere he could start.
Humphries started against Alabama in last year's opener, but tore a knee ligament. He tried to come back in the middle of October, but reinjured the knee, had surgery and missed the rest of the year.
