ENGLEWOOD, Colo. — Tight end Noah Fant still has a path to return from the Reserve/COVID-19 list ahead of Sunday's game, but he must receive two negative tests before the team leaves for Dallas in order to play this week, according to Head Coach Vic Fangio.

Fangio said Fant has yet to receive a negative test.

Under the NFL's COVID protocols for vaccinated players, an individual may be activated off the Reserve/COVID-19 list after he receives two negative COVID-19 tests separated by 24 hours.

Fangio said Thursday that Fant is vaccinated.

Guard Netane Muti also remains on the team's Reserve/COVID-19 list, and Fangio previously noted that Muti was vaccinated.

"They both feel fine," Fangio said. "They both have minor, minor symptoms. … I have texted or talked with both of them almost daily, and they both say they're fine."

Both players do not currently count against the team's active roster.

On the practice field, safety Caden Sterns returned to practice after missing Wednesday's session with a shoulder injury. Tackle Garett Bolles was the only player not to practice on Thursday.

Nose tackle Mike Purcell practiced for the second consecutive day after missing Denver's Week 8 win.

"He's doing OK," Fangio said. "It's always a little worrisome to have a guy out there with a cast on, especially when it's your thumb. But we'll see, because it'll obviously hinder him in tackling."

Defensive Coordinator Ed Donatell said if Purcell is able to play, he would wear a cast that allowed him the use of his fingers rather than a club.
