Steelers place T.J. Watt on COVID-19 list
His status for Sunday's game against the Baltimore Ravens is uncertain.
The two-time All-Pro returned to the Steelers' lineup Sunday against the Cincinnati Bengals after missing a game due to hip and knee issues.
Watt, a three-time Pro Bowler, leads the Steelers in both tackles for loss (13) and sacks (12).
The 27-year-old has tallied 41 tackles, four passes defended, and three forced fumbles in 2021.
