World Boxing Council super-middleweight champion David Benavidez returned a $250,000 signing-bonus check he received from Top Rank Inc. in Las Vegas on Monday, and will continue fighting under the banner of his promoter Sampson Lewkowicz and advisor Al Haymon’s Premier Boxing Champions, Lewkowicz told the Los Angeles Times.

Benavidez (20-0, 17 knockouts), boxing’s youngest world champion at 21, is scheduled to return to the ring in September in a mandatory title defense against No. 2-rated contender Anthony Dirrell.
