Houston Texans star J.J. Watt’s season was in doubt just a few months ago because of a torn pectoral muscle and Saturday he suited up and played, helping the team get a playoff win over the Buffalo Bills.

Watt had a key sack in his return to the field. Houston won the game in overtime, 22-19, thanks to 19 unanswered points from Houston in the second half.

“This is why you come back,” Watt said. “I don't know if I meant to come back for these many plays or this much extra time, but these feelings, these emotions, these fans, these players, Deshaun Watson and all the guys on this team, this is why you come back.”

Watt expressed his emotions in a series of tweets immediately after the game.

On Sunday, he thanked the fans for showing up at NRG Stadium. Houston’s next game will be on the road against the Kansas City Chiefs.
