Franceco Molinari and Padraig Harrington have withdrawn from the US PGA Championship at TPC Harding Park next week.
Neither player provided a reason for pulling out of the event but it means Harrington, who won the PGA Championship in 2008, has still not competed since March.
Talor Gooch, American golfer now 141st in the World Rankings, will replace Harrington at TPC Harding Park, while Troy Merritt, World No.153, will take Molinari's spot.
After much deliberation, I have decided not to travel to next week's PGA Championship.
The 2018 Open Champion made it clear in a statement that his planned move was keeping him from playing competitive golf, but he wanted to be back for the US PGA Championship.
As Covid-19 now looks to be under control in Ireland, I am taking the prudent approach by following the guidelines and reducing the risk as much as possible by staying at home.
The 2008 champion said he would be remaining in Ireland rather than travelling to San Francisco for what will be the first major of the year.
He says he'll watch every shot on TV instead. English pair Lee Westwood and Eddie Pepperell had previously confirmed they would not be taking their places in the field.
Harrington's primary disruption this year was related to the Ryder Cup, as he's the current captain of the European Team.
