Watt, who appeared to have his ankle retaped, then went to the bench before exiting the field while still in visible agony.

Fortunately, he was able to return to the game.

After the game, Watt discussed the sequence that got him injured.

The 29-year-old had seemingly been held during the play which led to his ankle issue.

Watt didn't hold back about the refs not calling a holding penalty in the sequence.

"I don't know, the NFL has something going against me so I don't want to talk any more negatively towards them," Watt said, via the Pittsburgh Tribune-Review.

"I don't know what I did, but, I'll leave it at that."

The Wisconsin product is second in the league with 14 sacks.

Pittsburgh also lost starting quarterback Kenny Pickett and linebacker Elandon Roberts to injuries during the contest.

Pickett will reportedly need surgery on his right ankle and could miss two to four weeks, per the Pittsburgh Post-Gazette.

The Steelers lost to the Cardinals, who had two wins entering the Week 13 game.

Pittsburgh will turn to backup quarterback Mitch Trubisky for the foreseeable future.

They'll have a quick turnaround as the 7-5 Steelers face the 2-10 New England Patriots on Thursday Night Football.
