Allen was placed in the NBA's COVID-19 health and safety protocols Sunday after testing positive for the virus, Adrian Wojnarowski of ESPN reports.
Allen was one of five Cavaliers to test positive for the virus Sunday, prompting the NBA to postpone the team's game against Atlanta later in the day due to the Cavaliers' inability to have the league-mandated eight players active for the contest. The 22-year-old center, who is averaging a career-best 16.8 points and 10.8 rebounds in 32.6 minutes per game, will most likely miss multiple games while in the health and safety protocol.
