UFC Hall of Famer and former champion Ken Shamrock said he’s ended his longtime feud with adoptive brother Frank Shamrock to work on a hush-hush MMA project he believes will “challenge a lot of the top promotions.” “I think this is something that the MMA fans have been waiting for and that they deserve,” Shamrock recently told MMAjunkie.com Radio (www.mmajunkie.com/radio). “They shouldn’t have to choose. They should love both and be able to share in both.” Shamrock (28-15-2) said the two discussed their contentious past and mended fences while filming the project earlier this month. “We sat down, and we had some discussions, from childhood to the fight, to the argument, to the separation, to the not going to my dad’s funeral (and) the reasons why,” he said. “We hashed it out right there on video, and there’s a lot of stuff in that that’s emotional.” The adoptive brothers fought their last respective bouts in 2010, but they’ve remained at each other’s throats for more than a decade.
