With Efrain Escudero on the bench due to a rib injury sustained in training, American Top Team lightweight Gleison Tibau will step in to fight Jeremy Stephens.

Sources close to negotiations alerted MMAWeekly.com of the change.

The fight is the second in three months for Stephens, who himself stood in for injured teammate Hermes Franca to face Joe Lauzon at UFC Fight Night 17 in February. Stephens lost by submission in the second round.

Tibau fought on the undercard of the February Fight Night, defeating veteran Rich Clementi by Guillotine Choke in the first round. The win snapped back-to-back losses against top lightweights Tyson Griffin and Joe Stevenson at UFC 81 and 86, respectively.

Overall, Tibau carries a professional record of 16-6 over a seven-year career.
