Washington Football Team head coach Ron Rivera is not pleased with his squad's poor vaccination rate.
"I'm truly frustrated. I'm beyond frustrated," Rivera said Tuesday, per Nicki Jhabvala of the Washington Post. "Part of the reason I walk in with a mask on is I'm immune-deficient. ... I just hope that our guys can understand that."
Rivera noted he is at risk after receiving cancer treatment last year, per David Aldridge of The Athletic.
According to Jhabvala, Washington had the lowest rate in the NFL with only 60 percent of players vaccinated as of Monday.
