TJ Watt is having another incredible year with the Pittsburgh Steelers. Unfortunately, he has been dealing with injuries throughout the season.

Entering Thursday’s game against the Minnesota Vikings, Watt 16 sacks and 16 TFL. That is already Watt’s career-high mark for sacks in just 11 games played.

Though Watt started the game against the Vikings, he was unable to finish the game. He was ruled out after leaving action in the first half due to a groin injury as the Steelers fell into a big early early on.

On Friday morning, NFL insider Ian Rapoport reported that Watt will go through more tests to determine the extent of his injury:

“He was questionable early with a groin injury, and if that sounds familiar, this is something that has happened to Watt at least 2 other times this season,” explained Rapoport. “He has missed time with a groin injury, it has always been minor, he’s been able to be back. It is unclear how minor this injury is…he’s going to have more tests (Friday).”

In 11 games, Watt has 48 tackles, 16 sacks, 16 TFL, and 4 forced fumbles. Entering the weekend, Watt leads the NFL in sacks and is tied for the league lead in TFL.

If he is able to get back on the field quickly, he should remain in the running for the Defensive Player of the Year Award.
