Kelly made the trip to Alameda to meet with the Oakland staff, despite two offers sitting on the table. With the Raiders, unlike his two other stops, Kelly would presumably be elevated to the number one role - he would sit behind Leonard Pope in Arizona and Alge Crumpler in Atlanta.
The 30-year-old tight end, considered a high-character player with excellent leadership qualities, has been mulling each offer in turn and it is not certain whether Oakland has offered a contract.
He caught 21 passes for 254 yards last year - the second highest total of his eight-year career. Back in 2000, Kelly was on the receiving end of 31 passes.
He is also a solid blocking tight end and does not complain about doing the little things to win games. He is the type of guy that would add instant chemistry to the locker room - a trait that is making a comeback in Oakland under new head coach Lane Kiffin.
Oakland signed wide receiver Ronald Curry to a new 5-year deal, $20 million contract. Currey caught 62 passes last season to lead the team.
