Columbus Crew SC announced on Wednesday evening that four players tested positive for COVID-19 after undergoing Polymerase Chain Reaction (PCR) tests, per MLS protocol. No other additional positive tests were received for players or staff at the time.

After two players initially tested positive for COVID-19 last Sunday (Nov. 22), they self-isolated and extensive contact tracing and facility sanitization occurred. After having Monday off from training, two additional players tested positive after Tuesday’s testing and began their own periods of self-isolation.

Columbus will continue testing each day this week, and they’re slated to train Friday and Saturday. The club is then scheduled to host Nashville SC on Sunday (8 pm ET | TV & streaming info) in an Eastern Conference Semifinal as part of the Audi 2020 MLS Cup Playoffs.
