Tiger Woods apologized after he was fined an undisclosed sum by the European Tour on Monday for spitting on the green during the final round of the Dubai Desert Classic.

The tour said in a statement that tournament director Mike Stewart reviewed the matter and "feels there has been a breach of the tour code of conduct."

"The Euro Tour is right - it was inconsiderate to spit like that and I know better," Woods said on Twitter. "Just wasn't thinking and want to say I'm sorry".
