The NFL and NFLPA have agreed to reduce the isolation time for players who test positive for COVID-19 down to five days for all players. 

The agreement includes both vaccinated and unvaccinated players and is contingent on the player being asymptomatic, or at least demonstrating that his symptoms are resolving, after the five-day period.

Under the previous protocol, unvaccinated players were required to isolate for 10 days from when they test positive. Vaccinated players can "test out" of isolation sooner than five days. 

Since Dec. 13, approximately 515 players have tested positive.
