Proctor sustained a concussion during Sunday's game against the Jets, Alain Poupart of SI.com reports.
Proctor played all 65 of the Dolphins' offensive snaps in Week 7, but he suffered a concussion somewhere along the way. He'll now need to clear the NFL's five-step concussion protocol to return to game action. Until then, 2024 sixth-rounder Jarrett Kingston is a candidate to step up at guard.
