Oliver (knee) has been ruled out ahead of Monday's game against the Rams, Joe Buscaglia of The Athletic reports.
The veteran defensive lineman will miss his second game of the season, this time due to a knee injury that he picked up during the Bills' Week 4 loss to the Patriots. DeWayne Carter and Greg Gaines should both see more defensive snaps in the absence of Oliver, whose next chance to play is Week 6 against the Raiders on Sunday, Oct. 18.
