**DALLAS -- Mavericks owner Mark Cuban said Tuesday he will vote against the Sonics' proposed relocation to Oklahoma City.

Sonics owner Clay Bennett has filed a relocation request with the NBA and a subcommittee of three NBA owners plans to recommend approval when all 30 owners vote on the Sonics' request on April 18.

A simple majority of the 30-member board is required to receive approval.**

Cause for concern?...Nah

Will help the Dallas-OKC rivalry for sure..Probably a good move for him even though he knows he will be one of the only ones voting no
