UFC 98 Headliner Frank Mir has been forced out of his highly anticipated rematch with Brock Lesnar due to a knee injury he suffered in training. Mir has already had surgery on his knee and is expected to be sidelined for 4-6 weeks.
It is unclear at this time if the UFC will find a replacement for Mir or just scrap the fight altogether and find a replacement for the main event.
A big hit for the UFC, who earlier in the week announce the event on their website.
