No regrets for Shane McGuigan over Carl Frampton and David Haye splits
McGuigan will oversee George Groves' first defence of his WBA super-middleweight title on Saturday, when the 29-year-old fights to reach the semi-final of the World Boxing Super Series by defeating Jamie Cox. The fight represents McGuigan's first at world level since those splits, which came during a period in which he was established among Britain's leading trainers.
