The Denver Broncos' injury woes continue to mount.
In additon to center Dan Koppen's season-ending torn anterior cruciate ligament and cornerback Dominique Rodgers-Cromartie spraining his ankle, tight end Joel Dreessen is going to have another arthroscopic surgery on his left knee..
He's expected to miss the rest of training camp, according to USA Today.
The Broncos are also without tight end Jacob Tamme due to a quadriceps injury.
The Broncos are also evaluating the merits of former college basketball player turned tight end Julius Thomas, a fourth-round draft pick from two years ago.
