The Carolina Panthers made four more roster moves Tuesday to reach the NFL mandatory 75-player limit and none of them came as a surprise.

   The Panthers placed defensive end Rondell Biggs, an undrafted rookie, on injured reserve and placed wide receiver Josh Davis on the reserve/non-football illness list. They also waived-injured receiver Justin McCullum and waived running back Marlion Jackson.

   The Panthers must trim 22 more players from the roster by Saturday.
