Rory McIlroy was docked $3 million (€2.7m) for withdrawing from this week's RBC Heritage under new PGA rules regarding "designated events."According to Golf Digest and Sports Illustrated, the fine is for a second absence from a designated event and will be withheld from the $12 million (€10.9m) payment to McIlroy from the Player Impact Program.The tournament began on Thursday at Harbour Town Golf Links in Hilton Head, South Carolina, and no reason was specified for the 33-year-old's withdrawal.The world number three missed the cut at last week's Masters after carding a five-over 77 on Friday.Any player ranked in the top 20 of the Player Impact Program are required to participate in designated events, a change the tour made last season as part of a string of counters to LIV Golf's emergence.Players are allowed to skip one designated event for personal or professional reasons, but McIlroy already sat out of the season-opening Sentry Tournament of Champions in January.
