The Miami Dolphins placed starting safety Isa Abdul-Quddus on injured reserve Wednesday, which ends his season.
Abdul-Quddus suffered a neck injury in Sunday's overtime win over the Buffalo Bills.
Abdul-Quddus was quietly one of Miami's best free-agent pickups in the offseason. He started 15 games and finished with 78 tackles and two interceptions. The safety also played his best football and took on a leadership role in the secondary when former Pro Bowl safety Reshad Jones was lost for the season with a shoulder injury.
The Dolphins are now without their two starting safeties from Week 1.
