Moore applied for a hardship waiver after leaving Pittsburgh in the offseason and received news that he could play today.
"The NCAA has granted a legislative relief waiver for senior J.J. Moore to be able to compete immediate for [Rutgers] in 2013-14," Rutgers said in a statement.
Moore joined the Scarlet Knights in the summer, and played in the Jersey Shore Basketball League, but was not cleared for in-season action until this week. Moore averaged eight points and three rebounds per game with Pittsburgh last season. He projects as a starter in Eddie Jordan's first year running the Rutgers program.
