Buffalo Bills coach Sean McDermott said Friday that defensive lineman Ed Oliver will miss Buffalo's Week 2 game against the New York Jets due to an ankle injury. Oliver is expected to miss multiple weeks while he recovers, according to ESPN .

Oliver's foot was stepped on during practice, and he was spotted wearing a walking boot Thursday.

"It's unfortunate," McDermott said. "Things happen, come up through practice ... Unfortunate, but an opportunity for somebody to step up early in the year here and show us what they've got."

It's a tough blow for Buffalo's defense. Oliver has emerged as one of the NFL's top interior defensive linemen in recent years. He had six total tackles, one sack and forced a fumble in the Bills' season-opening win against the Baltimore Ravens on Sept. 7.
