UFC women’s bantamweight contender Raquel Pennington seemed like the obvious next candidate to challenge divisional champion Amanda Nunes. Unfortunately, that’s not gong to happen anytime soon.

Pennington (9-5 MMA, 6-2 UFC) suffered a broken leg in vehicle accident on Tuesday in Colorado. The accident happened just after verbal agreements were in place for a title bout with Nunes (15-4 MMA, 8-1 UFC) at UFC 219 on Dec. 30, Pennington’s management team told MMAjunkie. The news was first reported by Combate.

The incident comes just as Pennington was set to make a comeback from a more than year-long layoff. She defeated former champion Miesha Tate by unanimous decision at UFC 205 in November 2016, but afterward was forced to undergo shoulder surgery.

Pennington, No. 6 in the latest USA TODAY Sports/MMAjunkie MMA women’s bantamweight rankings, is still evaluating options on whether she’ll require surgery to repair the damage to her leg, a rep said.

Regardless, she’ll have to wait for the chance to extend her current four-fight winning streak, which is the second longest active run at 135 pounds behind champion No. 1-ranked Nunes’ six-fight winning streak.

An exact timeline for Pennington’s return to competition is unknown.
