Australia’s James Pattison is expected to miss the World Cup after suffering a nervous breakdown.

The 25-year-old batsman had just bowled an unbeaten 134 off 46 balls in the second Test against India on Wednesday when he went into a fit state and fell ill.

“He had an issue with his heart,” the Sydney Morning Herald quoted his doctor as saying.

Pattison had been told by doctors he had a mild heart condition.

It is not known whether he has any other symptoms, although he was taken to hospital for a check-up and is being monitored.

He will miss the first Test against the West Indies in Hobart on July 13.

The Australian Cricket Board (ACA) said on Twitter: “James Pattison, 25, is recovering well from a stroke, and will miss his first World Cup match in Hobarts.

The Australian Test squad will be reconvened on Friday, after which he will be assessed by an independent neurologist.”

Pattinson is yet to be interviewed by the team doctor, but has been advised to rest and not go into the field in any condition, the newspaper reported.

Pattisson has played in just six Tests this season and has only scored twice in his last five outings.

He was picked up after an international break in 2016 and captained the Aussies to a Test series victory over South Africa at Eden Park.
