Buffalo Bills quarterback Josh Allen took a hit and went into the medical tent against the Houston Texans on Sunday. Allen was brought down by his legs and his head bounced off the turf after throwing an incomplete pass in the fourth quarter.

Allen was evaluated for a concussion but came back into the game on Buffalo’s next drive just minutes later. As he struggled to complete a pass, fans could tell something was off with their star QB, and questions began being raised about whether Allen actually cleared concussion protocol before returning.

The Buffalo Bills and Houston Texans played in Texas in Week 5. The Texans had a 20-17 lead late in the game when Josh Allen tried to make a play and ended up smashing the side of his helmet on the turf.
