Sir Anthony McCoy keenly awaits a verdict on the effects of delayed concussion in sport following the recently-announced study from the International Concussion and Head Injury Research Foundation.
The now-retired 20-times champion jockey is one of a large number of former riders taking part in trials for the study, Concussion in Sport, which will investigate the correlation between those in sport that are susceptible to receiving blows to the head and long-term damage to the brain.
The screening process will initially focus on more than 200 retired jockeys from Europe, also including Dunwoody and fellow former National Hunt champions Peter Scudamore, John Francome and Stan Mellor.
Writing in his blog for William Hill, McCoy said: "There were times when I think that I got delayed reactions from concussions.
"There were times when I got up from the ground and my head was spinning, yet I knew where I was.
"But then half an hour later you could feel the effects of it. That's an important thing - to try and analyse what may bring on delays to concussion.
"The last time I was officially concussed was 1997 and I've had a lot of bangs to the head since then.
"You become aware of your reactions and what you need to do to survive."
