PITTSFORD, N.Y. -- Buffalo Bills star defensive end Mario Williams missed his second straight practice to have his sore foot evaluated by team doctors.
Coach Doug Marrone continued to be short on specifics regarding the injury on Monday. He would only say the tests were being conducted away from the Bills training camp facility in suburban Rochester. He added he has not yet received a report from doctors.
Marrone still didn't know which foot Williams had hurt, or how or when the injury occurred.
Williams was held out from participating in the Bills camp-opening practice a day earlier after he informed trainers that his foot was sore.
He then watched practice from the sideline with his helmet on.
Williams declined to comment about the injury, deferring questions to Marrone following practice.
