LAS VEGAS – Emanuel Navarrete recovered from a slow start Thursday night, but it wasn’t enough to beat Robson Conceicao on the scorecards.

The aggressive, awkward Mexican champion dropped Conceicao twice, yet he settled for a majority draw in their 12-round, 130-pound championship bout on the Shakur Stevenson-Edwin De Los Santos undercard at T-Mobile Arena. Judges Max De Luca and Chris Flores both scored the fight a draw, 113-113 apiece, and they both credited Conceicao for winning seven rounds.
