The CDC published a scientific paper on Monday jointly authored with medical experts from the NFL and NFL Players Association detailing the efforts to complete the regular season and playoffs without any canceled games. The paper references what the league did in terms of limiting the spread of COVID-19 among its 32 teams. "We have not seen any evidence of on-field transmission in NFL games or practices," Sills said. Of those, 21 were believed to have resulted from within-club transmission at a single team, requiring closure of that team's facilities. On Nov. 21, a league-wide adoption of the protocol was mandated though the end of the season.
