Please see below for a timeline of the injury updates from throughout the Broncos' preseason game against the Vikings.

2:06 p.m. MT: Reserve safety Trey Marshall suffered an ankle injury on the opening kickoff after helping make a tackle. After being tended to on the field by trainers, he was able to walk off the field under his own power. The Broncos announced he is questionable to return to the game.

2:56 p.m. MT: Marshall has been downgraded to out.

4:16 p.m. MT: Running back LeVante Bellamy suffered an ankle injury early in the fourth quarter and was attended to on the field by members of the Broncos' training staff. He is listed as questionable to return, the Broncos announced.

POSTGAME UPDATE: After the game, Head Coach Vic Fangio provided updates on Marshall and Bellamy, as well as safety P.J. Locke, who left the game in the fourth quarter.

"Trey sprained his ankle," Fangio said. "... P.J.'s fine. I think he just got the wind knocked out of him. And Bellamy, ankle, also."

He also spoke about recent injuries to other members of the running back corps, as Mike Boone suffered a leg injury that reportedly will keep him out at least four weeks and Melvin Gordon III did not dress for pregame warmups with other starters.

"He hurt his groin just a little bit the other day," Fangio said of Gordon. "I don't think it's anything serious."

Boone, meanwhile, could possibly be headed to injured reserve, Fangio said.

"I'm not sure yet," Fangio said. "He could be."

Injured reserve rules for the 2021 season allow teams to return an unlimited number of players from IR after three weeks of recovery on the list, as NFL Network's Tom Pelissero reported Tuesday. Players may be eligible to return from IR only if they are placed on the list after they make a team's 53-man active roster following the final day for mandatory roster cuts on Sept. 1.
