On Wednesday night, wide receiver Rishard Matthews asked the Titans for his release. The transaction has yet to be processed, but it’s “doubtful” that the team will find a trade partner for him, Titans reporter Paul Kuharsky hears (on Twitter). 
Presumably, then, it’s a matter of time before Matthews’ request for a release is granted. Once he’s cut, Matthews will be free to sign with any club of his choosing since he is a vested veteran.
Matthews surely has his reasons for wanting out of Tennessee, but the perception around the league may be that he quit on his team. With that in mind, it’s hard to see another team giving up a draft pick, even a late one, to add Matthews in the middle of the season. Instead, interested clubs are likely willing to wait things out and try to sign the receiver to a cheap one-year deal.
