KANSAS CITY, Mo. -- Right-hander Gavin Floyd is the latest White Sox pitcher to be set back by injury. Floyd went back to Chicago for an MRI, which showed no structural damage.

Manager Robin Ventura said Floyd has tendinitis in the right elbow/forearm area. He was scheduled to start Monday but is now tentatively scheduled for Wednesday, although that seems unlikely.

Dylan Axelrod will start Monday in Boston and Philip Humber will pitch Tuesday.

"Gavin was complaining about general soreness,'' Ventura said. "He got checked out OK and everything looks fine but he does have tendinitis.

"It shouldn't be a DL (disabled list) but you never know when he gets back to see how much soreness he has.''
