Dana White says ex-WWE star Jake Hager's Power Slap injury is probably worse than any in UFC history

Last year, Alexandre Pantoja lost the UFC flyweight title after injuring his arm in a stunning reminder of how unpredictable the sport can be.

The MMA promotion’s boss believes that an injury that took place before ‘The Cannibal’ gets his chance to reclaim the belt tomorrow night trumps all others.

Hager was knocked out in his second Power Slap outing in July, with his attempt to bounce back from this defeat ending in strange fashion.
