Nate Marquardt Out of UFC on Versus 4, Charlie Brenneman to Face Rick Story, New Main Event

It appears that Nate Marquardt won't be making his welterweight debut tomorrow at UFC on Versus 4 after all. He has forced to pull out of his fight with Rick Story, and will be replaced by Charlie Brenneman. And there's now a new main event for the card too. MMAJunkie has it:

Marquardt is a late scratch from Sunday's UFC on Versus 4 event, and opponent Rick Story (13-3 MMA, 6-1 UFC) will now instead meet Charlie Brenneman (12-2 MMA, 2-1 UFC) on the evening's main card.

With the late change, a highly-anticipated heavyweight bout between Pat Barry and Cheick Kongo has now been promoted to main-event status.

The reason for Marquardt's last-minute withdrawal, mere hours before he was scheduled to hit the scales at the event's official weigh-ins, wasn't immediately evident.

There has been no official notice from the UFC as of yet. Brenneman had been scheduled to face T.J. Grant on the undercard of the event, but his opponent was stricken by an illness and the bout was cancelled. He will now move up to the main card to face Story, who was a late replacement himself for Anthony Johnson.  Today's weigh-ins are not being streamed live so while you won't be able to catch the new pairing there, you can tune in tomorrow night to Versus to see Story and Brenneman battle.

Update from MMA Weekly:

“He was not medically cleared. It is nothing serious,” said Kelly Crigger, a representative of Marquardt’s management team at Alchemist Mixed Martial Arts. Crigger could not go into any further detail than that until Alchemist releases an official statement, which is expected shortly.
