According to a Reuters report , six-time European Tour winner Simon Dyson faces possible expulsion from that Tour for a violation of the rules last week in Shanghai at the BMW Masters.
The 35-year-old Englishman was disqualified from the BMW Masters  after TV viewers notified officials that Dyson tapped down a spike mark in his putting line with his golf ball.
A spike mark -- unlike a ball mark -- cannot be repaired when in the player's putting line.
Here's video of the incident:
The European Tour has announced that a disciplinary hearing will be held to decide Dyson's fate.
"If, following the hearing, the panel decides that a breach of the code (of behaviour) has been established, it shall impose a sanction that it considers appropriate having regard to the circumstances," the tour said in a statement.
"Such sanctions may range from a reprimand, a censure, a fine, a suspension of Membership, a suspension from participation in one or more tournaments or for a given period, or expulsion from The European Tour, or otherwise as the panel shall determine."
For his part, Dyson maintains he in no way "deliberately broke the rules."
"My action was in no way a deliberate act with the intention of breaking the rules," he said in the Reuters report. "It was simply an accidental mistake."
