Former PGA Tour professional Brandel Chamblee, an analyst for the Golf Channel, has decided to take a step few other commentators or journalists would take by suggesting that Woods is "cavalier with the rules".
In a sport which treats such accusations with the utmost seriousness, it is a bold allegation by Chamblee and one which could well have Woods consulting his lawyers.
Woods has been at the centre of several controverses this year. At the Abu Dhabi Championship in January he was penalised two shots for taking an illegal drop.
Then at the Masters he took another illegal drop and signed for an incorrect scorecard. He was not disqualified but was given a two-stroke penalty - officals saying that there had been "exceptional circumstances."
The following month he gave himself a favourable drop at the Players Championship and in the BMW Championship in Chicago he contested a two-shot penalty for causing his ball to move while clearing away a twig.
Chamblee, using the analogy of how he himself had once cheated in a school exam and was downgraded to an F, said he would give Woods an F if he was writing a report card.
Chamblee then wrote in the US magazine Golf: "I remember when we only talked about Tiger’s golf. I miss those days. He won five times and contended in five majors and won the Vardon Trophy and - how shall we say this - was a little cavalier with the rules."
Woods was unavailable for comment last night.
