Few fighters can claim to have dealt with the wild ride Carlos Condit has been on since fall 2011. Originally scheduled to face B.J. Penn at UFC 137, Condit soon saw his co-headlining spot turn into a main event bout for the UFC welterweight title after Nick Diaz was pulled out of his scheduled bout champion Georges St. Pierre. Condit then stood helplessly by as he watched GSP withdraw due to injury, Diaz slide back into the top contender’s slot, and St. Pierre go down again for health-related reasons. As a result, the 27-year old is now poised to fight Diaz for the interim belt this weekend at UFC 143 instead of Josh Koscheck who he’d originally began preparing to face.

Condit opened up about the experience in an interview with the UFC promoting his fight with Diaz where he said, “I just had to kind of smile and shake my head. After everything that’s happened, all the ups and downs, honestly there wasn’t much else left to do but kind of laugh.”

“The past couple of months have been without a doubt one of the craziest periods of my career…definitely an emotional rollercoaster,” he concluded.

In terms of what he sees as being the biggest challenge he’ll face against Diaz, a former Strikeforce champ who is notoriously difficult to finish and is on an eleven-fight winning streak.

“Mostly I’m impressed by his toughness,” said Condit. “He’s got some great skills. Good boxing, good jiu-jitsu, but just his warrior spirit.”

Fans can catch the two of them tussle at 10:00 PM EST when the PPV starts with undercard action on FX/Facebook beginning at 7:00 PM EST.
