Move over, Matt Serra. There’s a bigger underdog in town.
Early lines on UFC 153′s new main event, which features a light-heavyweight non-title bout between middleweight champ Anderson Silva and Stephan Bonnar, are lopsided in Silva’s favor.
Silva is a more than 13-to-1 favorite and has up to a 93 percent chance of winning the fight, according to BestFightOdds.com, a site that features betting lines from several online bookmakers.
At one point, Serra was a +700 underdog when he fought Georges St-Pierre for the title at UFC 69. The winner of “The Ultimate Fighter 4″ wound up scoring the biggest upset in UFC history when he unseated the champ.
Bonnar, who has won his past three fights but recently had signaled his imminent retirement, is up to a +850 underdog on several sites. That means he has an approximately 10 percent chance of winning the fight.
The pay-per-view headliner, which takes place Oct. 13 at HSBC Arena in Rio de Janeiro, drew a collective gasp from the MMA community when it was announced late Wednesday by USA Today Sports/MMAjunkie.com (www.mmajunkie.com).
Silva and Bonnar stepped up to fight on short notice when UFC 153′s top draws fell out due to injury. A co-main event fight featuring Glover Teixeira vs. Fabio Maldonado was added, as well, in addition to a heavyweight clash between Antonio Rodrigo Nogueira and Dave Herman.
Silva (32-4 MMA, 15-0 UFC) most recently defended his middleweight belt and earned his 15th consecutive win in the octagon by defeating Chael Sonnen in a rematch from their UFC 117 bout.
Bonnar (14-7 MMA, 8-6 UFC) bested Kyle Kingsbury this past November at UFC 139, which improved his current win streak to three following a trio of losses to Jon Jones, Mark Coleman and Krzysztof Soszynski, respectively.
