The lineup for UFC on Fuel 10 lost a preliminary pairing today after middleweight Ronny Markes was injured in a car accident. Markes was scheduled to battle Derek Brunson on tomorrow night’s card. No replacement will be tabbed given the short turnaround time.

MMAFighting was first to report the change, confirming things with UFC President Dana White. According to White, the wreck was serious enough to result in a concussion and back injuries for the 25-year old Brazilian.

White also confirmed Markes and Brunson will both be paid.

Markes is 14-1 and has come out with his hand raised in seven straight scraps. He is 3-0 in the Octagon including wins over Karlos Vemola, Aaron Simpson, and Andrew Craig.
