It appears the UFC has suffered a huge injury to a planned fight, as former Strikeforce heavyweight champion Alistair Overeem has been forced out of a planned meeting with Junior dos Santos at UFC 160.

Ariel Helwani of MMAFighting.com first reported news of the injury, but the nature of it was not disclosed.

It also has yet to be reported if dos Santos will remain on the card, or just push the fight with Overeem back to possibly in July.
