The team's starting tight end will be sidelined for the rest of training camp after suffering a setback with his surgically repaired left knee, The Denver Post reported Saturday.
Dreessen originally underwent arthroscopic knee surgery in late May. He will now undergo a second arthroscopic procedure to clean up the knee, a person with knowledge of the procedure told USA Today on Sunday.
It's a sudden turn of events for Dreessen, who had been practicing without any reported issues through Friday. He sat out the team's scrimmage on Saturday because of pain in the knee, according to USA Today.
The Broncos missed both Dreessen and Jacob Tamme at Saturday's scrimmage. The tight ends combined for 93 catches and seven touchdowns last season. Tamme has been sidelined since last week with a pulled quad.
It's unclear if Dreessen will miss the start of the regular season following his latest setback. At the very least, legitimate uncertainty now is involved.The Around The League Podcast is now available on iTunes! Click here to listen and subscribe.
