Former Massachusetts Sen. Scott Brown tells WBZ-AM he won't be a candidate for Massachusetts governor next year.

The former Republican senator and state lawmaker spoke Wednesday night on the ``NightSide With Dan Rea'' radio program.

Brown had been mentioned as a possible GOP candidate. Democratic Gov. Deval Patrick is not seeking a third term.

Brown had told supporters at the Iowa State Fair on Sunday that he is ``exploring a possible run'' for president in 2016.

Brown won a 2010 special election to fill the unexpired Senate term of the late Edward Kennedy. He lost in 2012 to Democrat Elizabeth Warren.

Another Republican believed to be weighing a gubernatorial bid is Charles Baker, the former CEO of Harvard Pilgrim Health Care and the 2010 GOP nominee for governor.
