Sporting Kansas City announced Saturday that a first team player has been test positive for COVID-19.

All other players and members of the club have returned multiple negative test results and do not have symptoms, the MLS club said.

The name of the player was not revealed.

Upon receiving an initial positive test result, the player self-isolated under a strict and comprehensive protocol. The player will remain in isolation until medically cleared and will be monitored daily by the club’s medical staff.

Sporting Kansas City also has implemented contact tracing ahead of the club’s home match against Minnesota United FC at 8:30 p.m. ET Sunday at Children’s Mercy Park.

The MLS testing protocol requires all players to undergo Polymerase Chain Reaction (PCR) tests every other day, including the day before each match. The confirmation of a positive COVID-19 case occurs when a player receives two consecutive positive test results.
