UFC Fight Night is back in Las Vegas this weekend, with Raul Rosas Jr. vs Raoni Barcelos as the headlining bout in a 5-round fight.

The two bantamweight fighters are heading into the USA clash in good form, with the fight scheduled for Sunday, September 27. The card gets underway at 07:00 AEST, but this is fight 12 on the schedule.

Quick Picks

Our pick: Rosas Jr to win

Value bet: Fight to go the distance

Long shot: Barcelos to win

Tale of the Tape

The contest pits Rosas’ elite pressure grappling against the most experienced, well-rounded opponent he has faced during his current five-fight winning surge.

Rosas is entering his first scheduled five-round contest, while Barcelos brings more than eight years of UFC experience to this showdown.

Rosas’ game is built around immediate pressure: getting into clinch-and-wrestling exchanges, chaining takedown attempts, advancing position and banking long spells of control.

Barcelos is a significantly more difficult stylistic assignment than Rosas’ recent opponents. The 39-year-old Brazilian is a seasoned black belt with a strong wrestling base, clean boxing and real stopping power.

But how do the two compare? Rosas’s figures are first…

• Age - 21 vs 39
• Height - 5'9" (175cm) vs 5'7" (170cm)
• Stance - Switch vs Orthodox
• Record - 12-1-0 vs 22-5-0
• KO Record - 2 vs 8

Betting Markets to Watch

The odds are likely to see Rosas Jr. as a pre-fight favourite, as he has rapidly moved from being a prospect to a credible ranked contender.

His recent victories have shown a developing ability to win in different ways, with his latest being an impressive victory over American fighter Font.

However, value may be found in Barcelos, as he is a different type of fighter and much, much more experienced. His age could go against him in this fight, but Rosas Jr. hasn’t had to fight a five-round UFC bout yet, and that is going to test the 21-year-old.

If he consistently defends the first shot and keeps the fight standing, Barcelos certainly has a chance. His takedown defence, composure and striking volume make him a dangerous competitor.

The fight to go the distance is the most likely route, with seven of the ten combined fights going to the cards.
