Watt was forced to leave the game in the third quarter after taking an awkward step on a pass rush. He had been battling a groin injury throughout the game.
Watt could be seen trying to persuade trainers to let him return to the game, but they would not let him get back on the field.
“It was terrible to not be out there with my teammates,” Watt said after the game. “I have been trying to do whatever I possibly can to be out there with them and I tried to do today whatever I could to be out there with them, but there comes a time when you are doing more harm than good and when you can't go, you can't go.”
The actual injury that Watt suffered has not been announced, but head coach Bill O’Brien called it a “significant groin injury” on Sunday.
Watt had been one of the most consistent players in the NFL in 2015, playing on 96% of the Texans’ snaps coming into the game. He racked up 57 tackles and 17 1/2 sacks this season.
