It was a hit parade Sunday, and the majority of the blows came at the Texans' expense.

Five players were forced out of the game with concussions during a painful 29-7 loss to the Jacksonville Jaguars at NRG Stadium, including middle linebacker Brian Cushing.

All three tight ends on the active roster are now in the NFL concussion testing protocol: C.J. Fiedorowicz, Ryan Griffin and Stephen Anderson. The Texans have rookie tight end Evan Baylis on the practice squad, but could need to make more than one roster move heading into a Thursday night road game against the Cincinnati Bengals.

Right offensive guard Jeff Allen left the game with a right ankle injury. Wide receiver Bruce Ellington also sustained a concussion and exited the game.

"It'll be tough," Texans coach Bill O'Brien said of the injury situation. "I just came off the field, so I'm not sure. I just don't know what the report is yet."
