J.J. Watt is done for the season after suffering a torn pectoral muscle in Sunday's victory over the Oakland Raiders.

The Houston Texans feared the injury was serious, according to sources.

"This game can be beautiful and it can also be brutal," Watt tweeted. "Absolutely gutted that I won't be able to finish the season with my guys and give the fans what they deserve. I truly love this game and can't stand letting you guys down. Thank you for all of the thoughts & well-wishes."

Watt appeared to injure his pectoral muscle while tackling Raiders rookie running back Josh Jacobs for a 6-yard loss in the second quarter. Watt left the field for the Texans' blue medical tent before running to the locker room.

The Oakland Raiders have traded Gareon Conley to the Houston Texans for a third round pick.

Conley struggled at cornerback during the Raiders' Week 7 loss at the Green Bay Packers.

Jalen Ramsey didn't travel to Charlotte with the Jacksonville Jaguars for their game on Sunday, but he did go to Houston.

Deshaun Watson posted an Instagram photo of himself with Ramsey.

Sitting between Watson and Ramsey is agent David Mulugheta, who told multiple reporters 20 days ago that Ramsey wants out of Jacksonville.

Ramsey is seeking a trade from the Jaguars.

A league source said Ramsey traveled to Houston to see a back specialist.
