ANTHONY TUPOU finished his career with the Roosters in physical and emotional anguish after he was hospitalised with a bruised kidney following the season-ending loss to the Warriors on Friday night.

In a painful aftermath to the Roosters' disappointing exit from the finals race, Cronulla-bound Tupou was rushed to an Auckland hospital after he suffered a suspected lacerated kidney.

He was discharged yesterday morning and allowed to fly home with the rest of the team yesterday afternoon.

Roosters captain Braith Anasta said he was "weeing blood - never a good sign".

Had the Roosters still been alive in the competition Tupou would not have played any further part, but club doctor John Orchard said the Test forward would be right to play in the end-of-season World Cup if selected in the Australian squad.

"It's still not 100 per cent by any means … he might be OK for [the World Cup], I think it's about four or five weeks away so he might be OK," Orchard said. "He stayed overnight in hospital but it was safe for him to fly back today.

"It was very close to [being lacerated] but fortunately it wasn't that severe. It was pretty close, he was pretty unwell last night."

Orchard praised Tupou's courage in what turned out to be his last game for the club before joining the Sharks on a four-year deal starting next season.

"He thinks it happened just before half-time. He played the second half with it," Orchard said.

"He thought he might have just had bruised ribs, but when he came off the field we suspected it might have been the kidney so we took him to hospital for scans."

Meanwhile, Roosters fullback Anthony Minichiello has tipped the Warriors' fairytale finals run to continue against Manly on Saturday night.

"I think they can beat them," he said at Sydney Airport yesterday.
