Nate pulled out of his fight with Story.
MMAjunkie.com (www.mmajunkie.com) has learned that 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 (6-2 MMA, 3-2 UFC) and Cheick Kongo (15-6-2 MMA, 8-4-1 UFC) 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. However, Marquardt's camp did release a statement insisting the setback was temporary and his future still lies at 170 pounds.
"Nate is really disappointed," the statement read. "He really was looking forward to making his welterweight debut, and he plans to be back in there as soon as possible."
I wonder why he pulled out? Maybe it was a weight issue.
