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.
