By Nate Anderson: Unbeaten super middleweight prospect George Groves (3-0, 2 KOs) stopped former British challenger Paul Samuels (19-6-2, 11 KOs) in the 1st round on Saturday night at the Echo Arena, in Liverpool. Groves, 21, dropped Samuels with a big right hand in the 1st, and moments later knocked him off balance with a couple of punches that missed but still were able to get Samuels to stumble backwards into the ropes.
