Martin Gray, the tigerish midfielder who was so instrumental when Oxford United won promotion in 1996, has been forced to retire from the game because of a spine injury at the age of 30.

Gray left United in June 1999 to return north due to family problems, and joined Darlington while Malcolm Shotton was in charge of the U's.

Although taking a while to win over the United fans, his grit and determination got them on side - just as he was forced to go north for personal reasons.

The former Sunderland midfielder made the decision following a visit to the specialist in which he was told he could do permanent damage if he ever played again.

Gray was devastated by the news, but claimed he had little choice in the matter.

His blow was slightly softened by the news he has been appointed reserve team coach with the Quakers.

"It has been a nightmare ever since I picked up the injury against Chesterfield in January," he said.

"I had a long chat with the specialist on two occasions about a possible comeback, and he told me that if I injured the disc again, it would have to be removed.

"I had two choices - carry on playing with a 60-40 chance of crippling myself, or calling it a day. I can't afford to take the chance.

"This is the worst day of my career by a long way, but at least the chairman and the manager have softened the blow by keeping me at the club, which I'm really thankful for."

Former United boss Denis Smith, who was the manager when United were promoted in '96, was stunned at the news.

"I first came across him in non-league and noticed him because he looked like he was enjoying himself in every game and wanted to win," Smith said.

"His determination was second to none, and he was great to have in the dressing room. It's such a shame because he wanted it so badly."
