Mark Munoz suffered knee injury during Gegard Mousasi fight: 'It buckled during the first takedown'

Mark Munoz was dominated by Gegard Mousasi in the main event of UFC Fight Night 41, which took place last Saturday night (May 31, 2014) inside O2 World Arena in Berlin, Germany, on the promotion's new Fight Pass digital network. "The Filipinio Wrecking Machine" succumbed to a first-round submission (rear-naked choke).

Watch it again right here.

Munoz -- a decorated collegiate wrestler -- was expected to have a marked advantage on the ground, but was quickly rendered combat ineffective by "The Dreamcatcher," who stuffed the incoming shots and battered the former light heavyweight with punches in bunches.

Was a knee injury to blame?

"Mark will have his knee looked at when he returns to the states," according to a post on the middleweight's official Facebook page. "It buckled during the first takedown in the Munoz vs. Mousasi fight. When we receive the results of the MRI, we will update all."

Munoz (13-5) vowed to "pick up the pieces" following his loss to Mousasi, but I would imagine there is a growing sense of urgency within his immediate circle. Not only is the aging Filipino 36 years old, he's also 1-3 over his last four, with all three losses ending violently.

Chris Weidman blew him away with strikes, Lyoto Machida knocked him clean out with a head kick, and Mousasi handed him the first submission loss of his career. That's in addition to the fact that Munoz -- currently ranked No. 7 -- holds no wins over a top 10 fighter in one of the promotion's deadliest divisions.

If this old dog still has some new tricks, he better start using them.

Clock's ticking.
