CLEVELAND – An elevator mishap and late scratch has turned tonight’s UFC 203 event into a 10-fight card.

C.B. Dollaway (15-8 MMA, 9-8 UFC) has been forced to withdraw from a light-heavyweight matchup against Francimar Barroso (18-5 MMA, 3-2 UFC) due to a back injury. UFC officials today announced the news.

According to a statement:

“UFC announced that CB Dollaway has had to withdraw from his scheduled bout at UFC 203 due to an injury he suffered last night as a result of an elevator accident at a hotel in Cleveland. “UFC officials have been in communication with hotel management, and the hotel is currently evaluating and investigating the issues surrounding the incident.”

MMAFighting.com first reported the change. According to the report, Dollaway injured his back during the accident and was ruled out once he met with doctors. The extent of his injury wasn’t immediately known.

Following UFC 203 ceremonial weigh-ins on Friday evening, several fighters and their respective teams were stuck in an elevator. Dollaway can be seen in a video that circulated (via Instagram):

This led to Dollaway’s injury, which will prevent him from competing against Barroso on the FS1-televised portion of the preliminary card, which precedes the pay-per-view main card at Quicken Loans Arena in Cleveland.

UFC President Dana White first hinted at a potential problem when he shared a screenshot on Friday night from always-ready UFC vet Donald Cerrone, who offered to step in to fight (via Twitter):

Dollaway, a “The Ultimate Fighter 7” runner-up, was meant to make his UFC 205-pound debut after competing at middleweight for the entirety of his octagon tenure. He’s dropped his past three fights, sparking the change in weight class.

UFC officials didn’t confirm whether Dollaway or Barroso will be paid their contracted wage, or whether the matchup will be rescheduled for the future.

The late scratch marked the second fight to fall off the UFC 203 card during fight week. Flyweight Ian McCall was also pulled from the card after opponent Ray Borg was hospitalized due to illness.
