ENGLEWOOD, Colo. -- Just hours after the Denver Broncos had returned from their 25-13 victory over the Indianapolis Colts, coach Vance Joseph said Friday that Trevor Siemian is headed to injured reserve with a left shoulder injury and that Joseph hasn't decided whether Brock Osweiler or Paxton Lynch will start at quarterback Christmas Eve against the Washington Redskins.
"I'm not sure, we've got two healthy guys there,'' Joseph said. "We'll have a staff meeting on Monday morning and kind of see who's best for us. Obviously Paxton being a young guy, we want to see him play more. So that part will have some bearing there. So we'll see.''
Siemian left Thursday night's win in the first quarter after being sacked by the Colts' Barkevious Mingo. Siemian landed on his non-throwing shoulder and did not return to the game. He had surgery on the same shoulder last offseason.
Joseph said with Siemian now on injured reserve the Broncos "probably'' wouldn't add a third quarterback to the roster.
But having already missed the playoffs for the second consecutive season and with plenty of roster decisions to make in the coming months, Joseph said the Broncos feel compelled to get Lynch some playing time. Lynch was the Broncos' first-round pick in 2016.
Lynch, who has dealt with shoulder and ankle injuries this season, has started one game this year, against the Oakland Raiders. He left that game in the third quarter with an ankle injury and was 9-of-14 passing for 41 yards to go with an interception when he left after 33 snaps.
Lynch made two starts as a rookie in 2016. Joseph had said the Broncos wanted to play the players who could "help us win games'' to close out the season and not just play young players who needed a look.
But Friday, Joseph said quarterback is different because it will be such a big part of the Broncos' offseason discussions. Joseph said the Broncos will decide Monday whether Osweiler or Lynch or both will play against the Redskins.
"I think where we are with quarterback, we have to kind of see where we are here,'' Joseph said. "That's obviously a major decision moving to the offseason, so that's different in my opinion, when it comes to the quarterback. Now, we're not going to forfeit games so whoever's playing for us, our goal is to win the football game. Whoever is playing Sunday afternoon we want to win the football game, whether it's Paxton or it's Brock.''
That is a bit of a tough break for Osweiler given he had one of his better showings in relief of Siemian Thursday night. Osweiler was 12-of-17 passing for 194 yards with two touchdowns and he had an 18-yard rushing touchdown as well.
"Brock played really well [Thursday] night, he made some big-time throws, his leadership showed, he played with great poise,'' Joseph said. "He took care of the football, that's going to be a long and hard conversation.''
Osweiler, who had three starts earlier this season before he was moved aside for Lynch to start against the Raiders, was asked following Thursday's win if he believed he had earned another start.
"You know, unfortunately that's not up to me to decide, but certainly I would love to be the starter of this football team. I take great pride in coming to work every day and trying to be a great teammate for these guys. I love being a Denver Bronco, so if it was up to me I would love to play. Unfortunately, I don't make those decisions."
