On Monday, Kubiak downplayed the injury, saying he believed Siemian would return Tuesday. Holding Siemian out of passing drills is likely precautionary -- if he were truly injured, he wouldn't have participated at all.
Despite the missed throwing session, Siemian is still in line for the start in Saturday's tilt with the Los Angeles Rams.
Naming the seventh-round pick the starter for the third preseason game signifies that Siemian enjoys a lead over Sanchez to win the starting gig to open the season. The competition is far from over, however, with all three quarterbacks expecting to see plenty of playing time Saturday.
