A heavyweight division attraction has been added to UFC 184 as Frank Mir stands across the octagon from Antonio Silva. Mir will enter the fight riding a four fight winning streak and he has not earned a victory in just over four years. Silva has only won just two of six fights under the UFC banner and he will enter the fight on a two fight losing streak. UFC 184 takes place on February 28th from the Staples Center in Los Angeles, California with Chris Weidman and Vitor Belfort headlining.
