Watt was listed on the injury report as questionable for the game against the Panthers with a calf injury. He didn’t practice on Wednesday or Thursday and was limited in practice on Friday.

NFL on FOX reporter Jay Glazer said Watt started to feel off on Wednesday and went to the hospital Thursday to get his heart "shocked back in."

He played in two games this season with two sacks, three tackles and a pass defended this season. The Cardinals defensive end only played in seven games in 2021. He had one sack and 15 tackles. He jointed the Cardinals ahead of the 2021 season after spending most of his career with the Houston Texans.
