Rams head coach Sean McVay said Wednesday that Stafford is in the concussion protocol, Jourdan Rodrigue of The Athletic reports.

EDGE Analysis

Stafford struggled to move the offense during this past Sunday's 16-13 loss at Tampa Bay, where he completed 13 of 27 passes for 165 yards and one touchdown, was sacked four times and overall took eight quarterback hits. Now that he's in the concussion protocol, Stafford is subject to its five phases in order to gain clearance for game action. Wednesday's injury report may give an indication of Stafford's current standing in the protocol. If he's able to practice Wednesday in a limited capacity, he could be on a path to playing Sunday versus the Cardinals.
