AMA Fight Club's Rafaello Oliveira will make his third appearance in the Octagon at UFC Fight Night 21 in March, as he will fill in for the injured Cole Miller to face Andre Winner on the preliminary portion of the card. News of the change was first reported by MMAWeekly.com.

Miller is reportedly dealing with an undisclosed injury and there is no timetable yet for his possible return.

Miller was looking to build off a first round submission victory over Dan Lauzon at UFC 108 on January 2. The performance earned Miller "Submission of the Night" honors and moved him to 3-1 in his last four bouts, with his lone loss over that stretch coming in his previous bout against TUF 8 champion Efrain Escudero at UFC 103 in September.

Oliveira (10-2) is 4-1 in his last five bouts, most recently scoring a unanimous decision win over John Gunderson at UFC 108 in January. His lone loss over that span came in his previous bout, which was his UFC debut, against Nik Lentz at UFC 103 this past September.

Oliveira has been competing professionally for five-years, competing for other notable promotions such as Arena Fight, Rumble on the Rock and Xtreme Fighting Championships. He has finished seven of his 10 career wins with his only other career loss coming against Strikeforce lightweight contender Lyle Beerbohm at an ShoXC event in October 2008.

Winner (10-3-1) picked up his first UFC win in his last bout by scoring a brutal first-round knockout over Roli Delgado at UFC 105 in November. The win snapped a three-fight winless streak, which included a loss in his official UFC debut against Ross Pearson in the lightweight final of The Ultimate Fighter reality series at TUF 9 finale in June.

UFC Fight Night 21 takes place on March 31 at the Bojangles' Coliseum in Charlotte, North Carolina, and the event will serve as the lead-in on Spike TV for the debut episode of The Ultimate Fighter 11.

The event is headlined by a very interesting lightweight match up between former title contender Kenny Florian and former Pride champion Takanori Gomi. In addition, TUF 10 winner Roy Nelson will take on rising prospect Stefan Struve in a heavyweight bout set as the night's co-feature.
