Terrible news for the Cleveland Browns -- the team will be without head coach Kevin Stefanski for its first playoff game in 18 years ... he just tested positive for coronavirus.
And he's not the only one ... 2 players and 2 assistant coaches have also tested positive for COVID-19 -- and the team has shut down its facility while contact tracing is underway.
The timing couldn't be worse for the Orange & Brown -- which is set to take on the Pittsburgh Steelers in the AFC Wild Card playoff game on Sunday.
Losing Stefanski is a major blow -- he's a candidate for NFL's Coach of the Year, leading the Browns to an impressive 11-5 record, the team's best season in forever.
