Last week, BoxingScene.com reported that Lucas 'Machine' Matthysse was potentially going to face Mauricio "Maestro" Herrera as part of the HBO Pay-Per-View undercard for Saul 'Canelo' Alvarez's defense of the WBC middleweight world title against British superstar Amir 'King' Khan. The event is happening at the brand new T-Mobile Arena in Las Vegas, Nevada.

According to reports in Argentina, there is a new player in the mix to face Matthysse - Mexican welterweight Pablo Cesar Cano (29-4-1, 21KOs), who is best known for his battles with Erik Morales, Shane Mosley, Paulie Malignaggi and Ashley Theophane.

There is no guarantee that Matthysse-Cano would end up landing on the Canelo-Khan card, but it's very possible.

Matthysse (37-4, 34 KOs) is coming off a knockout loss in his junior WBC welterweight title bout with unbeaten Viktor Postol last October. Matthysse was stopped in the ninth round. He is now looking to switch weight divisions by moving up to the welterweight limit of 147-pounds.

Cano fought in December in Mexico, where he won a ten round unanimous decision over Silverio Ortiz (who went the distance last week with Frankie Gomez).

Herrera is reportedly now in talks for a rematch with Ruslan Provodnikov. They faced each other in January 2011, when Herrera handed Provodnikov his first career defeat. Matthysse won a close decision over Provodnikov early last year.
