Louis Gaudinot is a late scratch from Saturday’s UFC Fight Night 54 lineup, and the promotion is now seeking a replacement for the upcoming card.

Gaudinot (6-3 MMA, 1-2 UFC) was slated to fight flyweight Patrick Holohan (10-0-1 MMA, 1-0 UFC) at the event.

Sources close to the fighters confirmed the change with MMAjunkie. The sources spoke on the condition of anonymity because the UFC hasn’t made a formal announcement. A reason wasn’t given for Gaudinot’s withdrawal.

Report coming to @MMAjunkie shortly, but Louis Gaudinot out of Halifax card. @ufc looking for North America-based replacement ASAP. — John Morgan (@MMAjunkieJohn) September 28, 2014

UFC Fight Night 54 takes place at Halifax Metro Centre in Halifax, Nova Scotia, Canada. The main card airs on FOX Sports 1 following prelims on FOX Sports 2 and UFC Fight Pass. Holohan kicks off the main card.

Holohan made his UFC debut in July at UFC Fight Night 46 in his home city of Dublin. He submitted Josh Sampo in the first round and got a massive ovation from his home fans. The win kept the fighter, who’s a member of the SBG Ireland camp, unbeaten as a pro and was his eighth submission win in 10 victories.

Gaudinot looked to return following a suspension after failing a drug test (diuretic) after a win over Phil Harris at UFC Fight Night 37. That submission win was overturned to a no-contest, leaving Gaudinot winless since a May 2012 victory over John Lineker.
