According to our Field Yates, Bengals TE Jermaine Gresham has been missing the past few weeks because he's been recovering from hernia surgery performed earlier this offseason. He had previously missed the first two organized team activities, both open and voluntary, with an injury coach Marvin Lewis declined to give specifics on.
Fellow tight end Tyler Eifert returned to practice after missing the last open OTA with a shoulder injury. He was limited for part of Tuesday's workout, though. After beginning the session in uniform, he shed his jersey in the final hour to conduct conditioning exercises off to the side.
Gresham finished as the #21 TE in 2013, while Eifert finished #29. Eifert has far more upside, but lacks the experience of Gresham and may not get his chance to shine until Gresham is out of the picture.
