Australia’s cricket hierarchy hold no fears for Michael Clarke’s long-term future despite injury costing him a chunk of the looming West Indies tour.

Coach Mickey Arthur was awaiting results from scans on Clarke’s left hamstring on Wednesday but conceded the early prognosis “doesn’t look great”.

Clarke strained his left hamstring while making a century in Australia’s eight-wicket loss to Sri Lanka in the second tri-series final on Tuesday night.

Already ruled out of the finals decider against Sri Lanka on Thursday, Clarke will miss at least the early part of Australia’s one-day series in the West Indies starting on March 16.

Paceman James Pattinson is also in doubt for the five-match limited-overs series against the Windies – a strained buttock muscle is expected to sideline him for 10 days.

Clarke only returned from a strained right hamstring last Sunday.

His hamstring ailments are linked to long-term lower back problems but Arthur was not overly concerned at the injuries.

“Michael is the most professional guy I’ve certainly seen in my time in terms of the way he manages his body (and) the way he goes about his treatment,” Arthur told reporters in Adelaide on Wednesday.

“He is very methodical and very professional, so he has got every chance to keep getting it right.

“We were just looking through the stats last night, funnily enough, when we were having a chat – I think Mike has missed 15 ODIs through injury (but) he hasn’t missed a Test yet.

“That is a pretty good record, so no area for concern just yet.

“He’s always on top of his game and he’s always making sure he’s looking after that department.”

While the results of Clarke’s latest scans might not be publicly released until Thursday, Arthur said “it doesn’t look great for certainly the early part of the one-day series in the West Indies”.

Clarke conceded his return from his right hamstring strain was rushed but Arthur maintained it was worth the risk.

“When you get to the finals, we were always prepared to risk a player in order to win a final,” Arthur said.

“So I certainly think it was worth the risk.”

Arthur was also waiting on results from scans on Pattinson, who strained a glute muscle while diving in the field on Tuesday.

“He dived for a ball on the boundary and just pulled a glute … that will probably be seven to 10 days, not serious,” he said.

Australia’s squad departs for the West Indies on Friday.
