Kellen Winslow Jr.'s agent rejected a contract offer -- potentially worth at least $40 million -- from the Cleveland Browns yesterday that would make him the highest paid tight end in NFL history.

Winslow, the No. 6 overall pick in April's NFL draft from the University of Miami, was not on the field as the Browns opened training camp in Berea, Ohio.

In an unusual move designed to put pressure on Winslow's agent, Kevin Poston, Browns President John Collins released a statement before the club opened camp to announce that the Browns had made their "best offer" to Winslow.

The Browns said their offer would "far exceed" the $31 million deal Kansas City tight end Tony Gonzalez signed in 2002. That package included a $10 million signing bonus.
