Broncos’ undrafted free agent tight end Austin Fort suffered a torn ACL in Thursday night’s preseason game against the Seahawks, a source tells ESPN.com’s Adam Schefter (on Twitter). Of course, it’s a season ending injury, so Fort will have to wait until at least 2020 to make his true NFL debut.

Prior to the injury, Fort was impressing in training camp and was pushing hard for playing time on the roster. The Wyoming product was even getting time as a first-stringer in practice due to injuries.
Fort suffered the ACL tear after catching a beautiful 29-yard pass from fellow rookie Drew Lock. He went down quickly without contact and doctors confirmed the team’s worst fears soon after.
Fort’s injury leaves the Broncos thin at tight end. As it stands, Troy Fumagalli and Moral Stephens are the only healthy tight ends behind Jeff Heuerman and Noah Fant. Heuerman, meanwhile, is dealing with a shoulder issue.
