The Floyd Mayweather-Canelo Alvarez Showdown has just gotten even better after Showtime Boxing announced on Thursday the WBC light welterweight championship battle between Danny Garcia and Lucas Matthysse in the undercard of 'the One' Pay-Per-View slate on September 14 at MGM Grand Garden in Las Vegas.

Garcia, who has defended his light welterweight belt three times and preserved his undefeated record after 26 bouts, might be facing the toughest challenge of his career yet when he fights hard-hitting Argentine - Lucas Matthysse.

Matthysse has been unbeatable in his last six bouts, collecting victories against solid opponents such as former featherweight champion Humberto Soto and light welterweight titlist Lamont Peterson. The Argentine boasts a formidable 34-2 record with 32 knockouts in his career. Matthysse recently demolished Peterson within three rounds of their non-title Welterweight showdown last May 18 in Atlantic City in New Jersey.

Meanwhile, Garcia is coming off a hard-earned unanimous decision victory over veteran slugger Zab Judah in their light welterweight championship bout at the Barclays Center on April 27.

The 25-year-old Garcia is considered as one of the best young boxers in the generation with a professional record of 26 wins and 16 knockouts. Garcia also collected victories against several highly-rated boxers such as Nate Campbell, Kendall Holt, Amir Khan and Mexican legend Erik Morales in two occasions.

According to boxing fans, the inclusion of Garcia-Matthysse bout made the record-breaking bout between Mayweather and Alvarez even more interesting. After generating $19.5 million in live ticket sales, 'the One' could go down in history as the biggest fight ever made.

"The days of [undercard novelty act] Butterbean are over," Golden Boy promoter Richard Schaefer told the Los Angeles Times. "This is the most expensive fight ever put as the second fight of a pay-per-view."

The showdown between Garcia and Matthysse could be a ticket for one of them to book a lucrative fight with Mayweather Jr, if the Michigan native becomes successful in his fight against Alvarez in the main event.
