The NFL postponed this week’s game between New England and the Super Bowl champion Kansas City Chiefs after "positive COVID-19 tests on both teams.” Patriots starting quarterback Cam Newton and Chiefs practice squad quarterback Jordan Ta’amu were both added to the NFL’s COVID-19 reserve list released on Saturday afternoon.

The NFL said Saturday that the game, originally scheduled for 4:25 p.m. EDT on Sunday, will be played Monday or Tuesday, a move that would be possible only if there is no wider spread of the disease on the rosters.

Newton has started all three games for New England. Ta’amu has not appeared in a game but would have spent time in meetings with Super Bowl MVP Pat Mahomes and the team’s other QBs.
