I think the UFC did hire for him, for like 12 seconds. He was doing a few videos on the UFC youtube channel for a minute anyway, but I never saw much after that; I guess it didn't last long.
His big UFC career lasted about as long as Ariel's 'lifetime ban'. Which was about one weekend.
Personally I think his analyses are horrible anyway, and also the way he immediately shit on Ariel when he got fired and acted like he was replacing him was kinda pathetic.
