"For the health and safety of all players and staff, Major League Soccer postponed the match until Nov. 4 at 10 p.m. ET.

"Following the first confirmed positive cases of COVID-19 on Sept. 24, the Colorado Rapids closed their training facility and have not trained since. All players and staff with confirmed cases of COVID-19 have entered self-isolation and the players and staff that have continued to receive negative results have remained in self-quarantine while following MLS health and safety protocols."

The Rapids suspended training late last week when a first round of positive tests came through that included one player and three staff, and placed them in self-isolation. MLS then took the step of postponing the Rapids match on Sunday. A source added that the Rapids had hoped to return to training by Friday.

The postponement on Saturday's Colorado-Portland match is the second since MLS teams began playing games in home markets following the MLS is Back Tournament, which concluded on Aug. 11. At that tournament, which was held inside a bubble in Orlando, both FC Dallas and Nashville SC were forced to pull out due to a cluster of confirmed positive tests.

Since then, there had been less than a handful of confirmed positive tests. The Chicago Fire announced on Aug. 21 that one of its players had a confirmed positive test. More recently, FC Cincinnati said on Saturday that one of its players had a confirmed positive test.
