He has a black belt in BJJ as mentioned above.
Belcher released a webinar of how he defended Palhares' leg locks so I'm guessing Lombard might have taken a look at that, it's no secret what he's going to do, and for all the crap Lombard gets for being a can crusher not one of Palhares victories still fight in the UFC Middleweight division, and only Dan Miller remains employed.
Palhares is the most mentally weak fighter I've ever seen and just gives up if his one trick doesn't work, not to mention he's a dirty fighter so hopefully he gets what's coming to him and Lombard blasts him.
