Man, things just aren’t coming together as hoped for this first UFC venture to Mexico.

Earlier this week, UFC Heavyweight Champion Cain Velasquez was forced to bow out of the main event of UFC 180, scheduled for Mexico City on  15 November.

Then, another of the event’s attractions, Joe Lauzon, reported that he would be unable to compete, as well.

Did you think it could get any worse for UFC 180, which sold out quickly and was still one of the year’s most interesting MMA cards?

Well, we got the answer last night: “YES! YES! YES!”

That’s right, Diego Sanchez, noted for his indomitable fighting spirit, eccentric exhortations (like repeatedly yelling “yes!” on the way to the cage), and 25 career MMA victories, has also pulled out of the event.

Sanchez, seen above in a face off with Gilbert Melendez before a 2013 bout, cited a knee injury as the reason he will be unable to compete at UFC 180.

The lightweight offered his apologies to fans via his Twitter account, describing the injury as a tear of the lateral collateral ligament:

Sanchez was originally to face Norman Parke at UFC 180, but Parke bowed out due to an injury earlier this month. Then Lauzon stepped in, and then was forced to step away.

The UFC has not named a replacement bout — instead, a preliminary bout between Edgar Garcia and Hector Urbina will be moved to the main card.

UFC 180 will move forward with eleven bouts, headlined by Fabricio Werdum vs. Mark Hunt for the UFC Interim Heavyweight title.
