Via The Denver Post:
Another starter has suffered a significant injury. Starting tight end Joel Dreessen had a setback in his recovery from kneecap surgery and will be out at least two weeks.
The Broncos' top two tight ends from last year, Dreessen and Jacob Tamme, didn't dress for the scrimmage Saturday. Tamme was sidelined last week with a pulled quad. They combined for 93 receptions in 2012.
With Dreessen and Tamme out, Julius Thomas started with the No. 1 offense Saturday. Virgil Green lined up with the No. 2 offense and made a terrific catch on an 18-yard throw from Brock osweiler. Jake O'Connell, a veteran signed a week ago, had a catch from No. 3 quarterback Zac Dysert.
Last year Dreessen proved to be one of the Broncos most potent weapons on offense. Per Pro Football Focus, Joel was the highest rated TE in the NFL with just one drop in 80 targets. He registered 41 receptions with 356 yards and 5 TD's--most of those scoring catches coming in the Red Zone.
Camp has already saw Julius Thomas take significant snaps with the 1's. Make no mistake Joel Dreessen remains the best all around TE on the roster giving the Broncos great flexibility in both 11 and 12 personnel as both a pass catcher and blocker. Look for Thomas to keep getting the reps in practice as Dreessen heals from his injury/surgery. Ultimately, I believe that all four Broncos TE's (Dreessen, Tamme, Thomas, and Green) will make the final 53-man roster. With both Dreessen and Tamme out, JT and Virgil have ample opportunities to shine.
