Josh Kelly overcame an early scare to preserve his unbeaten record.

The 2012 Great Britain Olympian scored a late knockdown while riding out an early facial cut to outbox Nicaragua's Wiston Campos over 10 rounds.

Scores were 99-90 (twice) and 98-91 in favor of Kelly in their welterweight heat Friday evening at Talking Stick Resort Arena in Phoenix, Arizona.

Kelly entered on the heels of a hard-fought draw with Ray Robinson in his United States debut this past June. His second consecutive stateside appearance didn't get off to a much better start, suffering a cut outside his right eye and along the bridge of his nose. The wounds were deemed the result of a left hand from his southpaw foe, although ultimately never a factor over the long haul.

Campos provided fits all evening, doing his best to time Kelly's hands-down defense while seeking to force a dog fight. Kelly wouldn't quite bite, although an aggressive surge late in round two saw the undefeated welterweight connect with a flush uppercut.

Much of the bout featured more posing and fouling than clean punching, although Kelly sealed the deal with a knockdown in the opening seconds of the 10th and final round. Campos was valiant in defeat, but is now just 1-5-1 in his last seven starts as he falls to 31-7-6 (19KOs).

Kelly advances to 10-0-1 (6KOs). On deck at his disposal is a shot at European (EBU) welterweight titlist David Avanesyan, with the two having previously agreed to terms but both accepting interim bouts before colliding at some point in 2020.

The bout streamed live on DAZN in supporting capacity to the super middleweight debut of Daniel Jacobs (35-3, 29KOs) versus a considerably heavier Julio Cesar Chavez Jr. (51-3-1, 33KOs) in a battle of former middleweight titlists.
