Houston Texans quarterback Tom Savage returned to the field for a series after taking what looked like a truly damaging hit from the 49ers’ Elvis Dumervil. After getting knocked over in his own end zone, Savage stayed on the ground with his hands shaking before being helped up.

Savage was ostensibly put through the concussion protocol, but then very quickly returned for the next Texans possession, which was a three-and-out. He was replaced by T.J. Yates after that, though Savage still attempted to run onto the field and had to be pulled back by team personnel. He is now officially out with a concussion.

Savage was also evaluated for a concussion during halftime of last week’s Houston game against Tennessee.
