Arizona Cardinals WR Michael Floyd (head) was cleared on the sideline to reenter the game in Week 3 Buffalo Bills, but he experienced a headache on Monday, Sept. 26, and entered the league’s concussion protocol.

Footballguys View: This situation needs to be monitored. Floyd doesn’t have a history of concussions, but the team is obviously being cautious with him now after experiencing a headache on Monday. We should know more about his availability later in the week.
