Shanghai: England`s Simon Dyson, who faces suspension from the European Tour for cheating, has withdrawn from next week`s Turkish Open.
The six-times European Tour winner is not on the final entry list for the $7 million event in Antalya, which means the Englishman`s season is over.
He is 68th on the European Tour`s money list, with only the top 60 qualifying for the season-ending DP World Tour Championship in Dubai in a fortnight.
Dyson`s withdrawal from Turkey comes in the wake of his disqualification from last week`s BMW Masters in Shanghai after he fixed a spike mark in the line of a putt.
The European Tour will hold a disciplinary hearing for Dyson at a date yet to be determined to decide whether the golfer should be further penalised.
Possible penalties range from a reprimand to expulsion from the Tour, but the prevailing belief among other players is that he is more likely to be suspended for several months.
Dyson, 35, released a statement earlier this week vehemently denying that he deliberately cheated, saying he had made an "accidental mistake".
