Robert Winston has returned to riding after a long spell out through injury and a battle against alcoholism.
Winston was a champion jockey contender before his injury
The 26-year-old rider looked set to play a major part in the Flat jockeys' championship race before breaking his jaw in a fall at Ayr on 6 August.
During his enforced absence, Winston also had treatment at an addiction clinic in Ireland after admitting to a drink problem.
He drew a blank on his return to the saddle at Lingfield on Monday.
"It is great to be back," said Winston. "I was drinking myself to death. I just couldn't control it.
"There have been some dark days, but I am surprised at myself. I thought it might take me a little while to get back into the swing of things fitness-wise, but it hasn't been too bad."
Winston was one of six jockeys arrested as part of the ongoing City of London police investigation into allegations of race-fixing.
All the jockeys have denied any wrongdoing, and have been bailed until early 2006.
