New Wigan signing Bryan Fletcher has been given the all-clear to resume training after undergoing emergency bowel surgery.
The 31-year-old Australian second row was let of hospital earlier this week.
"It was caused by an inflammation and could have been worse because half the cases are caused by a cancerous tumour," he said.
"As soon as the test results showed nothing serious, it was a massive weight off our shoulders."
Fletcher had only been in the country a few weeks with his wife, who is five months pregnant, when he was taken ill with what proved to be a rare, life-threatening condition.
"I thought it was food poisoning at first," he said. "It started off with a stomach ache and it got very painful. The doctor said it was like a contraction.
"All the other organs just spasmed. They told me if you don't act, you've got 48 hours. Fortunately, I was already feeling better when they told me that.
"It's called an interception where the small intestine was getting sucked up by the big intestine. It's very rare, there are only 15 cases in the world each year."
Fletcher, who joined the Warriors on a two-year contract from Australian side South Sydney, is expected to miss the first six weeks of the new season but coach Ian Millward is looking forward to getting him back.
"If he misses the first eight or 10 games, we've still 20 games left for him to play in," he said.
"If we can get out of the blocks and do well, it would then be fantastic for a bloke like Bryan to come in. And he has signed a two-year contract so we've got him for another season after this."
Meanwhile, full-back Kris Radlinski will miss the first month of the new Super League season with the knee injury which ruled him out of the second half of the 2005 season.
Radlinski recently visited a specialist clinic near Nice, in the south of France, for advice on the injury.
"I think the trip to France did him good," said Millward. "It will fast-track his recovery but he will probably miss the first four games of Super League."
