Former WBC light flyweight champion Edgar Sosa (37-6, 21 KOs) returns to the ring June 5th. Sosa will take on former world champion Roberto ‘Mako’ Leyva (27-11-1, 21 KOs) in a 10 round main event fought at a contracted weight of 115 pounds maximum. The two met back in 2007 where Sosa stopped Leyva in 4. It will be the first fight for Sosa since losing his title to Rodel Mayol in controversial fashion on November 21, 2009. Sosa suffered a fractured cheekbone after receiving a head butt from Rodel Mayol in the second round of their bout, which was stopped later in the same round with Mayol winning by TKO.
