RING number one-rated 140-pounder Lucas Matthysse and unbeaten welterweight boxer-puncher Keith “One Time” Thurman could wind up on the same card in separate bouts next month at the StubHub Center in Carson, California, according to Golden Boy Promotions CEO Richard Schaefer.

"I'm working on April 26. We do have that card at the StubHub Center in Carson California where it's going to be a great outdoor venue," said Schaefer in an interview with RingTV.com on Wednesday.

"My goal is to put the two biggest punchers in the sport on the same night, meaning Lucas Matthysse against somebody and Keith Thurman against somebody and I'm probably going to call that card 'Heavy Hitters.'"

A 25-year-old from Clearwater, Florida., Thurman (22-0, 20 knockouts) scored a ninth-round technical knockout over veteran gatekeeper Jesus Soto Karass, who was floored once each in the fifth and final rounds of their bout in December.

In his previous bout last July, Thurman scored a 10th round knockout of previously unbeaten Argentinean Diego Chaves, whom he dropped once each in the ninth and final rounds.

The 31-year-old Argentinean, Matthysse (34-2, 32 KOs) was last in the ring in September when he was dropped in the 11th round of a unanimous decision loss to unbeaten RING, WBA and WBC junior welterweight champion Danny Garcia.

Before falling to Garcia, Matthysse had built a 4-2 record with four knockouts against six current or former titleholders, having floored all of them.

Last May, Matthysse registered three knockdowns during a third round stoppage of IBF 140-pound beltholder Lamont Peterson in a non-title bout for his sixth straight win inside the distance.
