Just days before the franchise's first playoff game since 2002, Browns coach Kevin Stefanski has tested positive for COVID-19, the team announced on Tuesday.
Two additional members of the coaching staff and two players have also tested positive for the virus and the Browns have closed their facility while contact tracing procedures take place.
It is unclear if Stefanski will be available this Sunday in the team's wild-card round game against the Steelers, but the team said special teams coordinator Mike Priefer will serve as its acting head coach.
According to NFL Network's Mike Garafolo, offensive coordinator Alex Van Pelt called plays in training camp and is expected to call plays on Sunday if Stefanski is unavailable.
