[Kansas City.com] Left tackle Willie Roaf didn’t practice Wednesday, increasing the likelihood that he won’t be available Sunday when the Chiefs play the Eagles at Arrowhead Stadium.

“I’m not giving up on Sunday, but I can’t take off running, and that’s the problem,” Roaf said. “Iâ’m still dragging that leg. It’s a difficult situation. I just have to keep doing what I’m doing and hope it gets better.”

Roaf said he is concerned about aggravating his sore hamstring and missing even more playing time.

Jordan Black will start again Sunday if Roaf isn’t available. The Chiefs made a lineup change at right tackle Wednesday. Kevin Sampson replaced Chris Bober.
