Micah Hyde’s agent announced earlier in the day that the Pro Bowl safety will miss the rest of the season with a neck injury.
On Saturday afternoon, the Bills placed Hyde on injured reserve.
Hyde went to the hospital for observation Monday night after being hit in the head and neck area late in the third quarter. He was released later that night after undergoing medical tests.
The Bills announced the signings of defensive tackles Brandin Bryant and Prince Emili to the active roster from the practice squad.
The team also elevated cornerback Ja’Marcus Ingram and center Greg Mancz from the practice squad for Sunday’s game against the Dolphins. They were standard elevations.
