Mystery surrounds Rory McIlroy 'karma' tweet as Paddy Barnes rules out dig at boxers
Rory McIlroy has sparked intrigue after tweeting "#karma" before quickly deleting it.
The golfer posted the mysterious tweet just after 1pm on Wednesday before it was quickly removed.
But despite the removal it has led to speculation over what it might have referred to.
The current world number five pulled out of the Olympics citing Zika virus fears.
Meanwhile Paddy Barnes and Michael Conlan - who both were dumped out of the Games in shock defeats - joked online about McIlroy's absence in Rio.
Barnes tweeted a picture of himself with McIlroy's former fiancé Caroline Wozniacki at the opening ceremony and asked the golfer if they made a good couple.
While Conlan joined with Rickie Fowler - McIlroy's rival - saying he was a "p****" for not turning up.
However, Barnes was quick to say the tweet wasn't aimed at them.
Others have suggested it may have been aimed at the Irish Olympic boss Pat Hickey who was reportedly arrested over allegations of ticket touting.
All eyes will be on the four-time major winner's Twitter to see if he offers an explanation.
