Which horse is set to fill Mugatooâs void? Kris Lees is excited about what the spring has to offer. Picture: Mark EvansâGetty Images Comments Newcastle trainer Kris Lees will be without his stable star Mugatoo for the spring, but he believes heâs found a ready-made replacement. Mugatoo won’t be back until the new year after suffering a tendon injury when tailing off behind winter sensation Zaaki in the Group 1 Doomben Cup. It was a bitter blow for Lees and owners Australian Bloodstock after Mugatoo had risen through the ranks to become one of Australia’s best middle-distance gallopers over the past 12 months.
