STOCKHOLM (Reuters) - Khabib Nurmagomedov called time on his mixed martial arts career following a second-round submission win over Justin Gaethje on Saturday, leaving his gloves in the centre of the octagon to fulfil a promise to his mother.

He wore down his opponent with his constant forward pressure before mounting Gaethje and locking him in a triangle choke that rendered the American unconscious to extend his record to 29 wins and no defeats.
