A broken ankle has forced light heavyweight contender Antonio Rogerio Nogueira to withdraw from his UFC 109 main card matchup against Brandon Vera, according to Sherdog.
Vera is expected to remain on the February 6 card in Las Vegas and the UFC is currently seeking a replacement opponent.
A timeline for a return to the Octagon was not revealed for Nogueira (18-3), the twin brother of heavyweight Antonio Rodrigo Nogueira who made his UFC debut in November with a first-round knockout of Luis Cane, his sixth-straight victory.
Vera (11-4) rebounded from a 1-3 stretch by winning back-to-back fights over Mike Patt and Krzysztof Soszynski in 2009, but suffered a unanimous decision loss to Randy Couture in November at UFC 105.
“UFC 109: Relentless” is headlined by Randy Couture vs. Mark Coleman and also includes Josh Koscheck vs. Paulo Thiago, Nate Marquardt vs. Chael Sonnen, and Matt Serra vs. Frank Trigg.
