 Murphy has clashed with Stephen Maguire , another of the 2000 Young Players of Distinction , on several occasions . At the start of their 2004 Grand Prix match , there was an incident that resulted in Maguire being docked the opening frame . After they had shaken hands at the outset of the first frame , Maguire asked referee Johan Oomen for permission to leave the arena and retrieve his chalk , which he had forgotten . While Maguire was away , the referee and Murphy spoke before tournament director Mike Ganley arrived on the scene and docked Maguire a frame for technically not being ready to start at the scheduled time , which angered and surprised Maguire . Murphy refutes that the docking of the frame was down to him speaking to the referee . Maguire won the match 5 – 2 and later commented : " Rules are rules but I 've never heard of anything like that happening before " .
