Though nothing blockbuster will happen between now and then, there's still the possibility another tight end is signed to add depth behind Tyler Eifert and possibly a more capable run blocker.
Rob Housler could fit that bill, but after visiting with the Bengals last week, he left Cincinnati without agreeing to a deal. however, Geoff Hobson reports that the Bengals and Housler are still talking, but have also spoke with other veteran tight ends. Hobson also reports special-teams ace Cedric Peerman may still be brought back, even with the Bengals loaded at running back:
The Bengals are hoping to re-sign one of their special teams captains, running back Cedric Peerman, and they are talking to veteran tight ends in search of a blocker. Cardinals tight end Rob Housler doesn’t have that rep, but the Bengals, who could use an experienced pass catcher to back up Tyler Eifert as he returns from injured reserve, are talking to him. And head coach Marvin Lewis has said Jermaine Gresham remains an option as he recovers from surgery. The Bengals made an early foray in free agency, but couldn’t find a financial or physical fit.
The odds are still not in favor of Gresham being brought back, but if no other tight end signs and the Bengals can't land one in the draft, re-signing him will probably be the best option.
