The Bengals have signed first-round pick Jermaine Gresham. Gresham agreed to a five-year, $15.85 million contract Monday. Its value could reach $18.5 million with escalator clauses; $9.6 million is guaranteed. "I'm glad the signing will happen," said coach Marvin Lewis of the rookie tight end. "He'll work at it. We've got a lot of snaps for him to get accustomed and get back in. He'll take 50 percent of the snaps. He's part of the reason why we're out here, so it's good that he's here."
