PITTSFORD, N.Y. -- Bills coach Doug Marrone grew frustrated after facing a second consecutive day of questions regarding defensive end Mario Williams' absence from practice due to a sore foot.
After saying Williams was still having his foot evaluated on Tuesday, Marrone lost his patience after being asked a fifth and final question about the player during a 12 1/2 minute post-practice briefing with the media. The first-year coach cut off a reporter to announce he won't answer any more questions regarding Williams until he receives a medical report from team doctors.
"For me to speculate, I never speculate until I hear from the medical staff," Marrone said. "And I get frustrated, honestly, when it gets to a point where I feel like I've tried to explain myself in how I handle injuries, OK? I've answered the questions, and you keep coming at me, all right?"
Marrone has been short on specifics since Williams complained of a sore foot and was held out of the team's training camp-opening practice on Sunday.
Marrone said he's not spoken to anyone, including Williams, regarding the player's status. The coach has yet to say which foot Williams hurt, and how or when the injury occurred. He has also not specified where Williams is being evaluated, except to say he's not present at the team's camp facility in suburban Rochester.
Williams has not been spotted since the end of practice Sunday, when he declined comment and referred all questions about his injury to Marrone.
The Bills made a big splash in free agency in March 2012, by signing Williams to a six-year, $100 million contract.
Williams, however, had an inconsistent season, and was bothered by an injured left wrist, which he had surgically repaired during the team's bye week off in late October.
He finished the season with a team-leading 10 1/2 sacks -- seven of them coming after he had the operation.
