Austrian Stefan Koubek was disqualified from the Metz Open for comments he made to the tournament supervisor during Thursday's match with Sebastien Grosjean of France.
Koubek was leading the second-round encounter 5-7, 7-6, 4-2 when supervisor Thomas Karlberg ordered the umpire to disqualify him.
"On the first point of the seventh game, on Grosjean's serve, a Koubek forehand close to the baseline gave a 0-15 advantage to Koubek," Karlberg told a news conference.
"But the umpire realised Grosjean was in the way of the line judge, who was therefore unable to judge the point. In this case, the rule is to replay the point.
"Koubek disagreed and asked for the supervisor's intervention. He did not want to accept the rules and used strong language. I told him the match was over and asked the umpire to announce it."
Koubek was also disqualified in the second round of the French Open in 2000 and during qualification for the Paris Open in 2003.
Grosjean next faces top seed Tommy Robredo of Spain in the quarter-finals.
