Report: Trevor Siemian has sprained AC joint in shoulder

The early word on Trevor Siemian’s shoulder injury is that the Denver Broncos reportedly suffered a sprained AC joint in his non-throwing shoulder.

Siemian was slammed to the turf on a sack by Bucs defensive lineman Clinton McDonald in the second quarter Sunday (video here). He left the game and was replaced by rookie first-round pick Paxton Lynch.

Siemian will undergo more testing on Monday.

Kubiak said Siemian will be day to day. Hope to learn more tomorrow. Siemian told trainers he felt he could have gone back in if needed.

Siemian was 5 of 7 for 68 yards and a touchdown before leaving the game. Lynch threw for 170 yards and a TD in the Broncos’ 27-7 road win.

Lynch would get the nod as the starter if Siemian were to miss any time, but it’s too early to count out the former 7th-round pick.
