Thurman, Matthysse doubleheader

LAS VEGAS -- Golden Boy Promotions chief executive Richard Schaefer likes for his fight cards to have a theme. For example, Saturday night’s Showtime PPV card, headlined by an expected brawl between Canelo Alvarez and Alfredo Angulo, is called “Toe To Toe,” for obvious reasons.

On April 26, Schaefer is planning to call a Showtime card “Heavy Hitters,” because he is penciling in two of the company’s most exciting punchers to appear in separate bouts against opponents to be determined -- interim welterweight titlist Keith Thurman (22-0, 20 KOs) and junior welterweight banger Lucas “The Machine” Matthysse (34-3, 32 KOs).

Schaefer said he hopes to stage the event at the StubHub Center in Carson, Calif., which has been home to many exciting fights over the years, although the venue is not locked in.

Thurman had a breakout 2013, rolling to a shutout decision against former welterweight titlist Jan Zaveck last March, knocking out Diego Chaves in the 10th round to win an interim title in July and then mowing down Jesus Soto Karass in the ninth round of an exciting fight in December.

Matthysse, from Argentina, had been on a knockout binge, including a stunningly easy third-round knockout of junior welterweight titlist Lamont Peterson in a nontitle bout in May. But then Matthysse, although the favorite, lost a decision in a hard-hitting fight to junior welterweight champ Danny Garcia in September on the Floyd Mayweather Jr.-Alvarez card.

Schaefer declined to talk about potential opponents, but said he was excited about having two of boxing’s most fan-friendly fighters on the same card.

“These are two of our big guns,” Schaefer said. “We want to put them in with good opponents and watch the punches fly.”
