Denver Broncos tight end Joel Dreessen will miss the rest of his side's training camp with a knee injury, according to a report.
The 31-year-old had surgery on his left knee during the off-season but returned to training camp with no issues.
However, during a session on Friday, Dreessen pulled up with discomfort and tests proved that he will need another surgery to clear up the affected area, reports The Denver Post.
Last season Dreessen was an integral part of Peyton Manning's offense as he recorded 41 receptions and five touchdowns.
