Sculthorpe is set to miss the Tri-Nations for the second year running

Danny Sculthorpe has told BBC Sport that reports brother Paul could be forced to retire are wide of the mark.

Paul injured his right knee in the Super League win over Wakefield last week and could miss the Tri-Nations series for the second year in a row.

"A few people have said his knee injury is career threatening but that's utter rubbish," said Castleford's Danny.

"He is seeing a specialist in London today but it is just a clean-out of his cartilage and everything will be fine."

Danny added: "He probably won't go on tour with Great Britain, which is disappointing, but a couple of months off will do him the world of good in the long run."

Paul, a 28-year-old forward with St Helens, has spent more time than he would have liked on the sidelines in the last two seasons.

A two-time Man of Steel, the forward only featured in 16 games last season because of a knee operation and persistent hamstring and back injuries.

In addition, he was injured when he finally made his debut as Lions captain, limping off during the 46-14 victory over New Zealand in June.

"He feels like he has not done his job for Saints, and being Great Britain skipper has made it very hard for him," said Danny, 26.

"He has hardly played any rugby over the last two years."

The Tri-Nations Series, which this year is being held in Australia and New Zealand, gets under way on 14 October, with Britain's first Test against the Kiwis on 28 October.
