NFL chief medical officer Dr. Allen Sills said Tuesday that 94.1 percent of players have been vaccinated against COVID-19, via Tom Pelissero of NFL Network.
Sills said the goal is still to reach 100 percent.
"I think we're seeing a substantial effect, in a beneficial way, of the vaccines," Sills said Tuesday.
The NFL did not mandate vaccines for players, but the league created stricter protocols for those who were unvaccinated, including more frequent testing and travel restrictions.
