An injured foot has forced Hawaii's Yancy Medeiros out of his UFC 184 bout against Tony "El Cucuy" Ferguson on February 28 in Los Angeles. Taking Medeiros' place on the card at STAPLES Center will be veteran 155-pounder Gleison Tibau.

The 31-year-old Tibau, who is tied with Chuck Liddell and Randy Couture for the fourth most wins in UFC history with 16, is coming off his third straight victory, a decision win over Norman Parke on January 18.
