The corner could have pulled him out after the 2nd but the ref called it right. He gave Lawton every chance to win but got him out of there before he got seriously hurt.
Completely disagree with Spencer Oliver. I thought it was stopped just about right, in European/World title fights you have to give people a chance.
Sykes definitely needs a few more learning fights before taking on someone like Leva. Apart from Crolla he's only faced journeymen types. Burns, if he is at his best, could beat Leva.
