Tiger Woods reacts on the first hole during the final round of the Dubai Desert Classic golf tournament, Feb. 13, 2011.

*Tiger Woods issued an apology today via Twitter for spitting on the 12th green during the final round of the Dubai Desert Classic, an act which brought a fine from the European Tour.

Tournament director Mike Stewart reviewed the incident, seen worldwide on television and on YouTube [watch below], and decided that the former world number one and 14-time major champion had broken the tour code of conduct.

He was fined an undisclosed sum by the European Tour on Monday — an amount estimated to be between $400 and $16,000 for a minor breach, according to ESPN.com.

“The Euro Tour is right – it was inconsiderate to spit like that and I know better. Just wasn’t thinking and I want to say I’m sorry,” Woods wrote in a message posted on the micro-blogging site.

“Everyone was terrific all week, fans especially. Dubai is always a fantastic host. Just wish the week could have ended better.”

Woods failed to end a 15-month victory drought, firing a final-round 75 to finish in a share of 20th place, seven strokes behind winner Alvaro Quiros of Spain.

Woods will next try to win his first title since the sex scandal that led to his divorce in two weeks at the World Golf Championships Match-Play Championship, Feb. 21-27.
