A pair of key featherweight matchups have been added to July’s UFC 162 event, as former UFC lightweight champ Frankie Edgar (15-4-1 MMA, 9-4-1 UFC) faces Charles Oliveira (16-3 MMA, 4-3 UFC) and Dennis Siver (21-8 MMA, 10-5 UFC) meets Cub Swanson (19-5 MMA, 4-1 UFC).

UFC officials today announced the new matchups.

Featuring a middleweight title fight between current champ Anderson Silva and undefeated contender Chris Weidman, UFC 162 takes place July 6 at Las Vegas’ MGM Grand Garden Arena.

Edgar seeks his first win at featherweight after falling short in his first fight at the weight in a bout with current champion Jose Aldo. The former IFC lightweight champ is currently mired in a three-fight losing streak despite being competitive in the bout with Aldo and a pair of contest with current lightweight champ Benson Henderson. The fight will be Edgar’s first non-title fight since a December 2009 win over Matt Veach.

Meanwhile, Oliveira is also a former lightweight who now fights for the fourth time at 145 pounds. The Brazilian youngster opened his run in the division with stoppage wins over Jonathan Brookins and Eric Wisley before suffering a knockout loss to Swanson at this past September’s UFC 152 event.

Meanwhile, the Siver vs. Swanson winner will find himself in an enviable position at 145 pounds, and the matchup could very will prove a de facto No. 1 contender fight.

Siver, a former lightweight, dropped to 145 pounds one year ago and has since earned convincing decision wins over Nam Phan and Diego Nunes. Overall, Siver is 10-2 in his past 12 octagon appearances after opening up at a disappointing 1-3 mark.

Swanson is an eight-time WEC veteran who found a tough time establishing consistency during his time with the now-shuttered promotion. However, after transitioning to the UFC and suffering a submission defeat to current top contender Ricardo Lamas, Swanson has since rattled off four consecutive wins in matchups with Dustin Poirier, Oliveira, Ross Pearson and George Roop.
