Throughout the 2020 season, Rivera underwent seven weeks of treatment, consisting of three rounds of chemotherapy and proton therapy five days a week, but continued to coach the team.
According to ESPN's John Keim, he missed just three practices and was present for every game as Washington went 7-9 to win the NFC East.
