Reports in Ireland are claiming Rory McIlroy’s relationship with Caroline Wozniacki could have hit a rocky patch.

The Sunday Independent speculates that romantic issues and not teething pains are the reason behind McIlroy’s current woes.

The world number one stunned golf when he walked off the course after just eight holes of the second round in his defence of the Honda Classic in Florida.

McIlroy blamed his walk-off on a wisdom tooth pain – just minutes after he was photographed eating a sandwich on the course.

Close to tears, he also told a number of Irish reporters at the clubhouse that he was having a tough time mentally.

The paper claims that speculation is mounting that McIlroy’s meltdown is linked to his romance with tennis star Caroline Wozniacki.

McIlroy had said: “There’s not much I can say, guys. I’m just not in a good place, mentally.”

Reports on Sunday also claim that McIlroy will come clean on his latest issues at a press conference in Florida on Tuesday.

The Sunday Independent reports that tennis star girlfriend Wozniacki also crashed out of the Malaysian Open last week in what was one of the worst defeats of her career when she was beaten by a competitor ranked 186th in the world.

Former world number one Wozniacki claimed she was feeling unwell and had a high temperature.

The report adds that the pair, who are usually very communicative with one another over Twitter, have not publicly conversed on the social networking site for several days.

The Danish beauty was questioned about her future with the Irish golfer last week.

Asked about any marriage plans, Wozniacki replied: “I think that question will be for him to answer.”

Asked if she would accept if McIlroy proposed, she laughingly brushed off the question, saying: “This is getting personal!”

McIlroy’s current woes are being blamed on the ‘The Curse of Nike’ after his $250m deal to switch from Titleist to the multi-sports giant’s clubs in January.
