Memphis' Sept. 18 game against Houston is in jeopardy of being postponed or canceled due to a COVID-19 outbreak within the Tigers' football program, a person with direct knowledge of the situation told the Commercial Appeal on Friday. The person requested anonymity because no official announcement had been made.

The person said the Tigers have at least 20 within the program who have tested positive for COVID-19 and are currently in a 10-day isolation period, and have "at least another 20" people in quarantine due to contract tracing. Most of the players who either tested positive for COVID-19 or are in quarantine are on the defensive side of the ball, the person said.

The dramatic uptick in positive tests, according to two people with direct knowledge of the situation, has been attributed to a party bus that members of the team were on after last Saturday's season-opening win against Arkansas State. The people were granted anonymity due to the sensitive nature of the situation.
