Blake Austin has suffered a medial ligament injury and is doubtful to go on Great Britain’s tour of the southern hemisphere.
The 28-year-old was subbed off at half-time due to a knee injury in Warrington’s 14-12 defeat to Castleford in the elimination play-off on Thursday.
Austin suffered a medial ligament injury and although a timescale is yet to be put on his recovery, his hopes of representing his British family heritage this autumn are in doubt because it is a ligament injury.
Warrington coach Steve Price commented: “It looks like a medial ligament injury in the knee.
“I’m not sure what grading it is at this moment in time whether it is grade one or two, I’m not so sure.
“At half-time he just wasn’t right so we decided to make the switch.
“It’s a difficult one. It is a question you would have to ask Wayne and his medical staff but once we get the scans over the next couple of days then we will go from there. Hopefully it is nothing too serious.”
