Sergio Moraes vs Santiago Ponzinibbio

After five years, twelve fights, a stint in the welterweight Top 10 and, most recently, a 1-4 slump, Paulo Thiago's UFC career is on the line.

Sergio Moraes has been forced out of his bout with Santiago Ponzinibbio and will be replaced by newcomer Wendell Oliveira.

Featuring only one bout above the welterweight division, UFC Fight Night 51 lineup is complete with the addition of a bantamweight bout between Iuri Alcantara and Russell Doane.
