Tibau brings a wealth of experience to the match, holding a 33-14-0 record across his career. The Brazilian, now 42 years old, trains out of American Top Team and fights from a southpaw stance at five-foot-ten with a 71-inch reach. His grappling credentials are hard to dispute, averaging 4.08 takedowns per 15 minutes throughout his career. His striking output checks in at 1.95 significant strikes per minute at 31 percent accuracy, reflecting a game plan historically built around wrestling and control.
