UPDATE (4:39 p.m. Monday): Baylor football has postponed its game against Oklahoma State until Dec. 12 after 42 positive COVID-19 cases.

Twenty-eight players and 14 staffers have tested positive for the virus, Baylor athletic director Mack Rhoades said on SicEm365 Radio. In addition to the positive cases, 17 football athletes are now in quarantine, bringing the number to 59 people in the program who are unavailable. 

The program believes that there could have been a false negative test before the trip to West Virginia and it could have been transmitted during the trip to Morgantown, W.Va. Rhoades specifically said they're trying to identify whether the locker room, plane ride or team dinner could have been a superspreading event. 

The game against Oklahoma State has been cancelled, but it's unclear whether Baylor will be ready to play Texas on Oct. 24 as well. The team must field 53 football players and reach positional thresholds for a game to take place. The Bears have games scheduled every week between Oct. 24 and Dec. 12. If the Bears had to cancel another game, there would be no room left on the schedule for make-up games.

There is no plan at this time for Baylor football to cancel the season. Practice is officially suspended through Oct. 17. 

Original story: Baylor football's matchup against Oklahoma State, scheduled for Oct. 17, is postponed until Dec. 12 at McLane Stadium. 

"The significant increase in positive COVID-19 cases has led to concerns of an outbreak and the decision to suspend team practice through October 17," Baylor athletic director Mack Rhoades said. "Secondly, this has caused a position group to fall below the minimum threshold of available players." 

Baylor paused all football activities last week after a number of positive cases of COVID-19 within the program, becoming the first Big 12 school in-season to do that. Previously, the Bears also had to cancel a matchup with Houston due to COVID-19 issues. 

This is the first Big 12 conference game postponed due to the COVID-19 pandemic. 

The game means that if Oklahoma State or Baylor were to make the Big 12 championship game, the title matchup would need to be pushed back until Dec. 19, one day before the College Football Playoff pairings would be announced. 

The Cowboys are the lone undefeated team left in the Big 12, and one of three teams with an undefeated conference record. At this point, Oklahoma State ranks No. 7 in the nation. 

The Oklahoma State game was planned to serve as Baylor's Homecoming matchup. It's expected that there will now not be a Homecoming football game in 2020.
