Leon Lawson Jr., who sucker-punched Jose Uzcategui on Saturday after the fighter was disqualified for hitting Andre Dirrell after the bell, is being sought on one charge of first-degree assault and one charge of second-degree assault.

RingTV.com obtained the criminal complaint filed Saturday in District Court of Maryland for Prince George’s County. The 168-pound contest was televised by Showtime and emanated from the MGM National Harbor in Oxon Hill, Maryland.

Lawson, who is approximately 45 years old per the complaint, had not turned himself into authorities at time of publication.

The fracas started after Uzcategui was DQ’d by referee Bill Clancy after landing a blow that knocked out Dirrell, Lawson’s nephew, following the eighth round.

Lawson immediately sought out Uzcategui in the ring and landed a blindside left-handed haymaker that shook up the super middleweight contender. Lawson followed up with a right hand that missed its mark, and was finally stopped by Uzcategui’s cornermen before he could continue the attack.

Lawson faces up to 25 years in prison on the first-degree charge and up to 10 years and/or a $2500 fine on the additional charge.
