Former PGA winner Steve Elkington could be disciplined for 'regrettable comments' on Twitter

Australian golfer Steve Elkington could be disciplined for what he says was his inadvertent "use of language in relation to the Pakistani people" in a Twitter message.

Golf's governing body has begun an investigation.

Elkington, the 1995 PGA champion, tweeted an offensive term while criticizing the English city of Southport. He had been playing there in the Senior British Open at Royal Birkdale.

The 50-year-old Elkington apologized in a statement. The governing R&A says it has spoken to him about the "inappropriate and regrettable comments."

In a joint statement with the European Senior Tour and Champions Tour, the R&A says "the matter will be reviewed" before "any disciplinary action against the player" is considered.
