The Broncos were surprised to be down two additional starters on Sunday, as left tackle Garett Bolles and tight end Noah Fant missed the entirety or most of Sunday's win over the Panthers.

Bolles was the first affected, as the team announced Sunday morning that he would be questionable for the game with an illness. In his place, the Broncos started Calvin Anderson.

Fant also left the game with an illness, exiting in the first quarter.

Head Coach Vic Fangio said after the game that both players have been tested for COVID-19 and each has returned a negative test. Fangio also said the team has no indication that it is connected to any illnesses other players had earlier this week, but they believe it may be food poisoning.

"It was totally started this morning," Fangio said. "Found out about Bolles [Sunday morning]. We think it's just a stomach thing. We've tested him with that rapid test and everything for the COVID; he's not COVID [positive] as of this moment.

But even though early tests have come back negative, Fangio said the team will take extra precautions and have Bolles and Fant stay an extra night before taking a private flight back to Denver the next day, should they test negative again.

"He's going to stay the night. If he [tests] negative again tomorrow, he'll come back on a private flight, I believe — both him and Noah. Noah, his started later than Garett's, but he couldn't go after an early point in the game, there. So those two guys will be under the same [process], they'll be doing the same thing tonight and tomorrow.
