“Football has been my life since I was a teenage boy and ithas given me so many opportunities. Above all else, I love the game and countmyself very lucky to have been able to play at the highest level.
“While the news is devastating, I have much to be thankfulfor. I thank God that I am alive and I pay tribute once again to the members ofthe medical team who never gave up on me. I would also like to thank everyonewho has supported me throughout my career, and the Bolton fans who have beenincredible. I am blessed to have the support of my family and friends at thistime.”
