CBS Sports reported that the game between the Las Vegas Raiders and the Cleveland Browns will be moved to Monday night due to about 20 Covid-19 cases on the Cleveland team.

The Washington Football Team, which has 21 players on the Covid-19/reserve list, will have their game against the Philadelphia Eagles postponed until Tuesday.

The NFL has not made any schedule changes and has yet to respond to Forbes.

The Cleveland, Los Angeles and Washington teams will have an opportunity to get several players back on the field in time for their Week 15 game, as the NFL announced on Thursday a new policy that allows fully-vaccinated individuals to be released from quark more quickly than before. Several star players are currently out of action by Covid-19, including starting quarterback Baker Mayfield and former All-Pro Jadeveon Clowney on the Browns, former All-Pros Von Miller and Odell Beckham Jr. on the Rams, and starting quarterback Taylor Heinicke on the Vikings.

The National Football League has tightened its protocols but allows players to return quicker after testing negative.

According toForbes, the NFL has most-ever positive Covid-19 tests in a single day.
