Jake Butt Injury Reportedly Feared to Be Torn ACL

Denver Broncos tight end Jake Butt reportedly suffered a non-contact knee injury that the team fears is a torn ACL during a walk-through, according to NFL Network's Ian Rapoport and James Palmer.

Butt underwent an MRI Thursday and the team is awaiting the results. 

According to Palmer, the new injury is to Butt's left knee. The University of Michigan product missed the entirety of his rookie season after he tore the ACL in his right knee during the Wolverines' loss to Florida State in the 2016 Orange Bowl. 

Prior to the injury, Butt posted eight catches for 85 yards through the Broncos' first three games. 

In the event Butt is lost for the remainder of the season, the Broncos will lean on Jeff Heuerman as their primary tight end. 

Heuerman has five catches for 32 yards so far this season.
