Warrington and England captain George Williams has said he is "racing against the clock" to be fit before the end of the Super League season - with a World Cup to follow in the autumn - after confirmation that he will have surgery on a neck injury.
The 31-year-old's club had confirmed he would be out for an "extended period" with an injury sustained in the loss at Catalans on 18 April.
"I got a knock and didn't think it would be as serious as it was," the half-back told Sky Sports during Warrington's Super League game against Wigan on Friday.
"I went for a scan and it's not good news. I've had a couple of days to process it and obviously it's disappointing, but I'll have the surgery and look forward to hopefully the back end of the year."
Williams will leave Warrington at the end of the season to return to the NRL and, asked about his hopes of representing the Wire again this season, Williams added: "I'm praying with everything I've got.
"It wouldn't be a good way to go out and that's why the news was so tough to take. I'll be racing against the clock to get back and hopefully I can play here again."
