The New York Jets may have a troublesome situation on their hands with Muhammad Wilkerson.

Unhappy that he still doesn't have a long-term contract, Wilkerson won't sign his franchise-tag tender anytime soon and might not report for the start of training camp in late July, according to sources.

By rule, teams have until July 15 to sign franchised-tagged players to long-term contracts. Failing a new deal, the player must play for his one-year tender. In Wilkerson's case, it would be $15.7 million.
