Thirteen Broncos were listed on the team's injury report Friday, including quarterbacks Brock Osweiler and Peyton Manning.
However, both quarterbacks fully participated at practice on Friday, the Broncos said.
"He [Manning] was good," Broncos head coach Gary Kubiak said. "He practiced well. He took not only some reps for us offensively, but took most of the scout team for us. I think it was a good week."
Kubiak said Brandon Marshall and T.J. Ward are listed as questionable for Sunday's final regular season game.
However, Kubiak said everybody else will be listed as probable including Osweiler and Manning, Todd Davis, Omar Bolden, Owen Daniels, CJ Anderson, Demarius Thomas, Emmanual Sanders, Darian Stewart, Lerentee McCray and Vance Walker.
Marshall may still play, too.
"He practiced today," Kubiak said. "He looked pretty good, so I think we have a shot. He's come a long way, so we'll see where we are."
After playing on Monday Night Football earlier this week, the Broncos have a short week to get ready for Sunday.
"I think we have a tough, tough task on our hands this weekend," Kubiak said. "We have a really fresh team that we're playing. It's the last game of the year. Anything goes."
"Yesterday we were a little slower," Kubiak said. "But we practices good at the end of yesterday and we had a lot of energy today."
