Buffalo Bills lose receivers Isaiah McKenzie, Jamison Crowder to injuries

BALTIMORE — Buffalo Bills wide receiver Isaiah McKenzie will not return to the team's game against the Baltimore Ravens after being placed in concussion protocol Sunday.

Wide receiver is now a position of concern for the Bills. Fellow slot receiver Jamison Crowder was carted off the field with a towel on his head and his left leg in an air cast. He is doubtful to return with an ankle injury. Wide receiver Jake Kumerow is not active Sunday after suffering a high ankle injury in the Bills' Week 3 loss to the Miami Dolphins.

Only three other Buffalo wide receivers are active — Stefon Diggs, Gabe Davis and rookie Khalil Shakir.

McKenzie suffered his injury in the third quarter of the Week 4 game against the Ravens after catching an 8-yard pass over the middle on third down from quarterback Josh Allen. Multiple defenders were near McKenzie to make the tackle, and teammates immediately called over the team's athletic training staff to look at the receiver, who initially appeared to be motionless on the field. He had four receptions for 21 yards and a touchdown before leaving the game.

The Bills' starting slot receiver sat up about a minute later and then jogged off the field and straight into the locker room. After going down 20-3 in the second quarter, Buffalo has bounced back in the second half to tie the game at 20.
