(NEXSTAR) – New England Patriots quarterback Cam Newton has COVID-19 and the Patriots game against the Chiefs will not be played on Sunday.

The NFL said the game scheduled for Sunday will be rescheduled after “positive COVID-19 tests on both teams.”

ESPN’s Adam Schefter was first to report that Newton would miss Sunday’s game.

The team said the player has entered self-quarantine. Players, coaches and staff who were in close contact with him were tested Saturday morning and all were negative, the team said in a statement.

After a relatively healthy start to the season, COVID-19 has begun to impact NFL players ahead of Week 4. Earlier this week, positive test results on the Tennessee Titans forced the first coronavirus postponement of the season.
