BOSTON -- The White Sox placed right-handed pitcher Gavin Floyd on the 15-day disabled listwith right elbow tendinitis on Tuesday.

Philip Humber, who starts tonight's game against the Red Sox, was reinstated from the DL.

It's Floyd's first trip to the disabled list in his 11-year professional career. The move is retroactive to July 8.

Floyd is 7-8 with a 4.54 ERA and 91 strikeouts in 17 starts. He is 3-1 with a 1.37 ERA over his last four starts. He wasn't overly concerned about the soreness on Monday, when he said he was hoping to avoid the DL.

"We are thankful it's nothing serious, but I want to get back out there,'' he said.

The soreness first occurred while he was throwing during the All-Star break.

"I took two days off and I threw, played catch. It was there,'' he said. "The next day I felt better, but the next day I threw a bullpen and it wasn't, I was a little concerned.''
