Another key Pittsburgh Steelers starter has tested positive for COVID-19.
Fitzpatrick has started in nine games and has recorded a team-best 64 tackles, as well as one pass defended, one tackle for loss, and a forced fumble.
Fitzpatrick will need to be symptom-free and test negative twice before being allowed to rejoin the team upon his initial positive test results.
The former University of Alabama standout was scheduled to address the media at 12:00 p.m. on Monday but was unable to appear amid his positive test.
The Steelers are already without quarterback Ben Roethlisberger, who was placed on the NFL's reserve/COVID-19 list hours prior to Sunday's 16-16 tie against the Detroit Lions.
The Steelers later included Roethlisberger in a news release detailing inactive players for their Week 10 matchup shared on their official website Sunday morning, which also included wide receiver Chase Claypool, who experienced a toe injury during last Monday's (November 8) win against the Chicago Bears.
Roethlisberger has thrown for 1,986 yards, 10 touchdowns, and four interceptions during his 18th NFL season.
Pittsburgh was on a four-game winning streak prior to Sunday's tie against the winless Lions.
