Shane Lowry is to part company with his long-term caddie Dermot Byrne.

The Offaly native made the decision after failing to make the cut at the Open Championship in Carnoustie. 

Lowry and Byrne have worked together since 2009, with their partnership beginning just after the former won the Irish Open.

Lowry's coach Neil Manchip was on the bag during the second round at Carnoustie. 

With Lowry declining to speak to the media afterwards, a spokesperson for the player said: "Shane and Dermot have decided to take a break from working together for the upcoming schedule of tournaments in the US.

"We are currently exploring a number of options and a new caddie will be in place for the RBC Canadian Open next week." 

Lowry's form has dipped alarmingly of late and speaking to RTÉ Sport after his opening round at the Open he said: "I'm not enjoying my golf at the minute, and my golf is not really enjoying me and that's the way it is, and it's hard to take."
