UFC lightweight contender Jim Miller on Monday became the fourth Brazilian jiu-jitsu black belt under Renzo Gracie disciple Jamie Cruz, according to officials with the AMA Fight Club in Whippany, N.J.
The 27-year-old Miller has rattled off four consecutive victories since his unanimous decision loss to the unbeaten Gray Maynard at UFC 96. He last appeared in March, when he earned a unanimous nod over Mark Bocek at UFC 111. Miller owns other notable victories against Duane Ludwig, Matt Wiman and Bart Palaszewski. He will square off with American Top Team standout Gleison Tibau at UFC Fight Night 22 on Sept. 15 at the Frank Erwin Center in Austin, Texas.
Miller -- who has secured more than half (10) of his 17 career victories by submission -- trains alongside his brother, former International Fight League middleweight champion Dan Miller, and UFC veterans Charlie Brenneman, Ricardo Romero and Rafaello Oliveira at the AMA Fight Club.
