Thiago Silva out of St. Preux bout 24 hours after booking

It took less than a day for the

target="_blank">light-heavyweight bout between Thiago Silva and

Ovince St. Preux to fall apart. The UFC Fight Night match that

was planned for Jan. 15 in Duluth, Georgia has been officially

scrapped after Silva was ruled out for an unspecified reason.

The UFC announced the scratch

target="_blank">on Thursday night.

The fight would have been a fairly quick turnaround for Silva,

who fought on Oct. 9, defeating Matt Hamill in a three-round

unanimous decision in Barueri, Brazil. That victory marked the

second straight victory for the 31-year-old, who holds a career

record of 16-3 with 2 no contests.

The match with St. Preux was originally slated as the

night’s co-main event.

The UFC did not specify whether St. Preux would stay on the card

against another opponent or move elsewhere on the schedule. The

30-year-old St. Preux (14-5 overall) has won both of his Octagon

bouts since joining the organization earlier this year. He won his

debut with a technical decision over Gian Villante in April, and

came back in August with a first-round knockout of Cody

Donovan.

While the UFC hunts for a new co-headliner, the main-event

pairing remains set

Costa Philippou squaring off at The Arena at Gwinnett

Center.
