LAS VEGAS – Add Dennis Siver to the growing list of UFC featherweights who believe they’re just one win away from a title shot. As it turns out, Siver’s Saturday opponent, Cub Swanson , is right there with him. Siver (21-8 MMA, 10-5 UFC) and Swanson (19-5 MMA, 4-1 UFC) meet in a key contenders bout to open up the main card of UFC 162, which takes place at MGM Grand Garden Arena in Las Vegas. The main card airs on pay-per-view following prelims on FX and Facebook. Siver has won two straight at featherweight since dropping down from lightweight, where he spent 13 fights after a drop from welterweight and picked up five post-fight bonus awards in the UFC. Swanson has four straight featherweight wins and along with Ricardo Lamas believes he should be next in line for a shot at the 145-pound belt that Jose Aldo puts on the line against “The Korean Zombie,” Chan Sung Jung , in August. Lamas and Swanson believe they should be there ahead of Jung, as it is.
