"Really it's a reward more than anything. I mean, this kid does everything, scout team, there's not a rep he misses, whether he's playing DB, wide receiver. So, he deserves an opportunity to help us out," Kubiak said.
Now he's hurt again.
Siemian won the job in camp in big part because he can digest Kubiak's entire West Coast offense while Lynch is limited after operating such a basic spread offense in college.
Siemian finally returned to health last week following the bye, when he was able to get some rest and a second injection in his non-throwing shoulder.
"The biggest thing is to not overload him too much, let him be free and play. And like I said, the key is the football team playing well around him," Kubiak said.
Siemian will make the trip although he might sit in the coaches' box with offensive coordinator Rick Dennison rather than stand on the sideline because of the boot.
The Broncos are hopeful Siemian returns next week when they travel to Tennessee.

Kubiak wouldn't commit to a change at punt returner, saying only that Raymond would play.
It will sideline him this weekend.
Raymond, an undrafted rookie from Holy Cross, was promoted five days after the Broncos watched another speedster, Tyreek Hill, score against them on a rush,Fjallraven Australia Store, a reception and a return.
Siemian had hoped to return to practice Friday but head athletic trainer Steve Antonopulos informed coach Gary Kubiak his starter wasn't ready.
Although receiver Bennie Fowler (knee) is out for Sunday, Raymond's promotion gives the Broncos an astonishing eight wide receivers on their active roster to go with two long snappers and just five D-linemen.
Raymond aims to give the Broncos a similar spark.
Raymond could supplant Jordan Norwood as the Broncos' punt returner. Norwood had two muffs last week, one of which led to a safety and the other to a turnover at midfield and a shove in the back from teammate Aqib Talib.
"His speed is just crazy," said Lynch, who has worked with Raymond on the scout team.
ENGLEWOOD,Cheap Wholesale Shoes Free Shipping, Colo. (AP) — Trevor Siemian's biggest takeaway from his career-best performance wasn't the masterpiece of pinpoint passes in the face of heavy pressure but a sprained left foot he suffered on one of five sacks.
Lynch lost to Atlanta in Week 5 when Siemian was out with a bruised left shoulder. Lynch, a first-round pick out of Memphis, had a poor performance against the Falcons, and four days later, Siemian was back in the lineup at San Diego even though he lacked mobility and zip on his throws.
Kubiak said Lynch had a good week of practice but stressed "we need to play good around him. That's our job as a football team, to help him out."
The Broncos also promoted speedy wide receiver/punt returner Kalif Raymond from the practice squad with rookie fullback Andy Janovich (ankle) going on injured reserve.
The Broncos are scrambling for a playoff spot after their loss to Kansas City in which Siemian threw for a career-best 368 yards with three TDs and no interceptions. He was injured on his last sack, when Tamba Hali powered past Russell Okung to drop the second-year QB.
So, expect to see Lynch in the shotgun a lot Sunday. He's much more comfortable there rather than under center, where the Broncos have him lining up with one foot farther back to help with his raw footwork.
The Denver Broncos ruled out Siemian for Sunday's game at Jacksonville,Wholesale Buffalo Bills Jerseys, meaning rookie Paxton Lynch will make his second career start.
"I think it's still a day to day process,Air Max 97 Cheap Online," Kubiak said. "When we tried to get him going a little bit today we realized it was time to go ahead and make a decision" to start Lynch this weekend.
Lynch said Friday he's glad he's gotten his first game and the accompanying butterflies out of the way already: "It feels good to have game reps under your belt and I'm excited to go get another one,Wholesale Football Jerseys China," he said.
He'll be in a walking boot Sunday when the Broncos (7-4) turn to Lynch, who lost his debut eight weeks ago, against the Jaguars (2-9).
The coaching staff's message to Lynch is more "go win the game" than "go win the job."
"With my size and stature, speed is one of my assets," said Raymond, who's 5-foot-9 and 160 pounds. "If I can make that impact from a speed standpoint, that's what I plan to do."
