On Wednesday Reggie Kelly was placed on injured reserve after he underwent surgery on his left leg to treat his ruptured Achilles tendon.

The injury for the Bengals starting tight end occurred two days prior during one of the team’s non-contact drills. A full recovery is expected for the 11-year veteran by the beginning of next season.

Kelly’s injury was Cincinnati’s first significant one of training camp. Last year he caught 31 passes on 207 receiving yard, and was the Bengals’ third leading receiver.

Two other Bengals tight ends were injured on Wednesday. Ben Utecht, a reserve, suffered a concussion during Wednesday’s evening practice. As a precaution he was sent to the hospital. The injury occurred during one of the team’s full speed drills. It appeared that Utecht hit head to head with Darryl Blackstone, a linebacker. Utecht crumpled to the ground and was unconscious temporarily.

Utecht’s teammates knelt beside him as he was being strapped onto a stretcher and placed into an ambulance to be taken to the hospital. He was kept overnight for observation. Jack Brennan, Cincinnati spokesman, said that Utecht had full movement in his legs and arms.

Another reserve tight end, Daniel Coats, wound up with a sprained ankle, suffered in the morning workout and showed up at the evening session on crutches. After these injuries there are only two tight ends remaining- rookies Chase Coffman, a third round pick and Dairus Hill, a free agent.
