Tennessee placed Dupree on the reserve/COVID-19 list Monday, Jim Wyatt of the Titans' official site reports.
Dupree recorded a sack in his second straight game Thursday against the 49ers, but he'll now face the tough task of clearing the NFL's COVID-19 protocols ahead of the Titans' Week 17 game against Miami after he tested positive for the virus, according to Tom Pelissero of NFL Network.
