UFC fighter and former Ultimate Fighter season 1 competitor Nate Quarry has officially announced that he has retired from the sport.

The 39 year-old’s MMA career goes back as far as January of 2001 and includes a 10 fight run in the UFC between April 2005 and March of 2010 in which he compiled a 7-3 record.

During that time he managed to work his way up to a middleweight title shot against Rich Franklin, but it was a fight that didn’t go his way, being KO’d in such brutal fashion that the clip of him getting poleaxed has been highlight reel material for the UFC ever since and indeed was recently immortalized by being included in the promotion’s new introduction sequence.

Quarry knows what it’s like to be the one handing out the knockouts as well though, with five of his UFC victories coming from either KO or TKO.

In the latter fights of his career it became clear that Quarry, who had suffered a number of bad injuries during his career, was slowing down and so it comes as no surprise that he’s decided to hang up his gloves.

The good news for fans of ‘Rock’ however is that this is not the end of Quarry’s association with the sport as he’s recently started work as a co-host of Spike TV’s new ‘MMA Uncensored Live’ talk show.
