Bengals put TE Alex Smith on injury list, sign TE Kevin Brock

The Bengals put tight end Alex Smith on injured reserve Tuesday, ending his season and cutting deeper into Cincinnati's depth at the position.

Smith hurt his left biceps during a 24-10 win over Atlanta on Sunday. The Bengals (2-0) also are missing tight end Tyler Eifert, who is out for at least eight games with an elbow injury.

The Bengals signed free-agent tight end Kevin Brock to fill Smith's spot. The second-year player opened camp with Cincinnati and was waived on Aug. 26. He has played in six games with Buffalo and Kansas City.

The Bengals also released tight end Ryan Otten from the practice squad and signed offensive lineman Emmett Cleary, a first-year player waived by Oakland last month.
