Star forward Tim Cahill is in doubt for the Socceroos’ crucial FIFA World Cup play-off against Honduras after suffering an ankle injury in the A-League on Friday.

The Melbourne City veteran injured his right ankle in a clash with Sydney’s Jordy Buijs during his side’s 1-0 defeat at AAMI Park.

He was sent to hospital for scans, Fox Sports reported.

Cahill initially tried to play on after the knock but was forced to limp off the field midway through the first half.

Commenting on vision that showed Cahill walking out of AAMI Park, ex-Socceroo Robbie Slater said that it didn’t look good.

“He certainly looked to be limping, quite heavily,” Slater said on Fox Sports.

But while Cahill’s ankle was heavily strapped, he was walking unassisted.

Melbourne City teammate Stefan Mauk said that Cahill was “in good spirits” following the incident.

“I don’t think it was too serious – I hope not,” he said.

Cahill – who is Australia’s all-time leading scorer with 50 goals in 103 national team appearances – was scheduled to fly to Central America this weekend.

Australia play the first leg of their play-off against Honduras in San Pedro Sula on Saturday, November 11, before returning to Sydney for the return clash on November 15.

Fox Sports commentator Thomas Sorensen cast doubt on Cahill’s ability to play the opener.

“He’s such a massive player for Australia,” he said.

“I wouldn’t put it past him to be ready, maybe not for the first game, but the important home leg in a couple of weeks.”

The winner over two legs books a spot at next year’s World Cup in Russia, but the loser will miss out.

Despite Cahill’s advancing years, the 37-year-old’s importance to the Socceroos was shown when he netted both goals in a 2-1 win over Syria in October.

That victory booked Australia’s spot in the inter-continental World Cup play-off.
