A rumor originally popped up earlier this afternoon on Tatame.com, a popular Brazilian MMA site, and Yahoo! Sports has since confirmed the unfortunate news with UFC President Dana White.
The fight was originally scheduled to happen at UFC 108, but Silva’s elbow surgery delayed the fight.
As for a possible replacement, Chael Sonnen is a logical choice, but he is suspended until March 6 thanks to a cut from his fight with Nate Marquardt this past weekend.
If Sonnen is not cleared to fight, Silva could take a fight at light heavyweight, but many of the top stars in the division have been booked.
UFC 112 in the mean time, will be headlined by Frankie Edgar vs. BJ Penn for the UFC lightweight championship, with Renzo Gracie vs. Matt Hughes slotted as the co-main event.
