The WEC 50 fight card took a massive hit with Urijah Faber announcing via his Twitter account that a knee injury has forced him out of his scheduled match.

Former WEC featherweight champ Faber was set to make his bantamweight debut against Takeya Mizugaki in Vegas next month but that will now have to wait as “The California Kid” will be on the mend.

There is no word of a potential replacement yet but we will keep you update as more details are released.
