Rory MacDonald vs. Tarec Saffiedine free fight videos preview UFC Fight Night 54 contender's bout

One of these two men will be fighting for the Ultimate Fighting Championship (UFC) welterweight title in 2015 with a win in the UFC Fight Night 54 main event, which takes place this Saturday night (Oct. 4, 2014) inside Halifax Metro Center in Nova Scotia, Canada.

But will it be Rory MacDonald ... or Tarec Saffiedine?

It's pretty much a given that "Ares" will move on to face the winner of Johny Hendricks vs. Robbie Lawler, who collide for "Bigg Rigg's" belt at UFC 181 on Dec. 6 in Las Vegas, Nevada (more on that fight here). The same can't be said for "Sponge," though you can bet a win over MacDonald probably puts him just one fight away.

Simply put, there is a lot on the line this weekend in Halifax.

To help get mixed martial arts (MMA) fans pumped for this weekend's big bonanza, the promotion has wheeled out a pair of free fight videos, featuring both UFC Fight Night 54 headliners in action. First up is the interloper, who rocked-and-socked his way to a five-round decision victory over Hyun Gyu Lim way back in January.

Have a look:

Impressive.

Also doing work against a crafty international veteran was MacDonald, the hometown hero in this weekend's affair, who handily disposed of former middleweight No. 1 contender Demian Maia when they went to war earlier this year in "Sin City."

See for yourself.
