Kelly was released by the Raiders earlier this offseason.
“The club appreciates his service, dedication and toughness,” the team said.
Kelly signed a seven-year, $50 million deal in 2008, and would have made $6.5 million next season. Releasing him saves the Raiders $4.775 million, according to Rotoworld’s Nick Mensio.
A Raiders source told Rapoport that Kelly is a “helluva player at limited reps, especially if motivated,” and that he played too many reps in Oakland.
“Moves really well for a big man. Can still rush the passer, just needs to be disciplined within the system,” the source continued.
Kelly has spent all nine seasons of his career in Oakland. He was a Pro Bowl alternate in 2010 when he recorded seven sacks and 60 combined tackles.
However, his production dropped big time in 2012, when he only had 1.5 sacks and 46 combined tackles.
