According to MMAFighting.com, Belfort suffered an injury that will force him out of the fight. But, the UFC was quick to find a replacement, as Wanderlei Silva will step in to take on Le at UFC 139.

Wanderlei Silva will make his return to the Octagon on November 19 in San Jose, when he takes on former Strikeforce middleweight champion Cung Le at UFC 139.

UFC President Dana White announced today that Vitor Belfort had to pull out of his fight with Le because of an injury, and as a result Silva will step in and take it.

Belfort vs. Le had the makings of a great fight because of the speed and quickness both have in their striking.

However, Le vs. Silva should be just as good, if not better, because Silva is relentless and is willing to be knocked out in order to put on a show. Belfort is more hesitant in his striking. With Silva now in, expect fireworks and an explosive knockout when he and Cung Le face off.

According to UFC President Dana White’s Twitter account, Diego Sanchez is out of his co-main event bout with Matt Hughes at UFC 135 due to a broken hand.

White indicated that the UFC is searching for a replacement for Hughes, but just moments later, Josh Koscheck posted this on his Twitter account:

Oh ya 19 days then or something like that!!!! Either way it looks like I am in to fight matt Hugh if he takes it????

The blow is tough for Sanchez, who had won his last two bouts to improve to 23-4 in his career. A fight with Hughes gave Sanchez a chance to pick up a win over a Hall of Fame fighter and really put a stamp on his career. Sanchez was coming into the fight as the favorite to win.

Hughes (45-8) hasn’t fought since last November when he was KO’d by BJ Penn in 21 seconds. There don’t seem to be a lot of options left for Hughes in the octagon, but a fight with Koscheck wouldn’t seem too favorable for him.

Koscheck hasn’t competed since UFC 124 last December when he lost to Georges St. Pierre and suffered a broken orbital bone. Koscheck indicated he would be returning to action in November as a middleweight. Apparently plans have changed. Koscheck has the skill set to beat Hughes as his wrestling is on par with Hughes and his striking is far superior.

UFC 135 takes place Saturday, Sept. 24 from Denver.
