LAS VEGAS - Like the rest of the boxing world, Michel Rivera is very interested in Saturday night's welterweight showdown in Las Vegas.  The Errol Spence-Terence Crawford bout will have 4 major titles on the line and will produce an undisputed champion.

BetMGM has Crawford listed as a small favorite at -160 at the time of this writing.  Most observers see the fight as a true 50-50 matchup. 

While Rivera believes it will be a close fight, he believes that Crawford will pull away with the victory.

“It is going to be a very good and competitive fight. The way I see it is Terence has more abilities and I see him winning the fight. Terence is the more complete fighter in my opinion,” Rivera told

The 35-year-old Crawford is looking to become an undisputed champion in a second weight class.  He also achieved the feat in the super lightweight division and won his first world title as a lightweight.

Spence has fought his entire professional career in or around the welterweight limit of 147 pounds.  Rivera acknowledges that Spence also has advantages but doesn't think it will be enough to defeat the versatile southpaw from Omaha, Nebraska.

"That isn't to say Spence doesn't have a chance. He has his advantages too. He is more physical and is bigger and stronger than Terence. I imagine his power is better too but I still see Terence winning the fight,” Rivera explained.

The rest of the pay-per-view includes Isaac Cruz-Giovanni Cabrera, Nonito Donaire-Alexandro Santiago and Yoenis Tellez-Sergio Garcia.
