THURSDAY IS D-DAY FOR MAGUIRE Adrian Maguire will see a specialist tomorrow to discover how soon he can return to race-riding. The jockey was forced to give up his rides at Newcastle today after suffering back spasms at Musselburgh on Tuesday. Maguire's wife Sabrina said: "He's going to see a specialist tomorrow, he couldn't get to see one today, so we should know more then." Maguire, who only returned to action after a week off at Doncaster on Saturday, has said that he will not make a comeback until the problem is sorted out.
