BLAKE Austin has damaged medial ligaments in his knee during tonight's play-off defeat to Castleford Tigers.

The Wire stand-off was injured in the first half of the elimination play-off loss.

Despite limping heavily, the Australian made it to half time but did not reappear for the second half.

Wire head coach Steve Price says Austin will go for scans in the coming days to determine his availability for the upcoming Great Britain tour.

"It looks like a medial ligament in the knee. I'm not quite sure what the recovery time will be as it depends what grade it is.

"We don't know whether it's grade one, two or three

"I wasn't privy to what was going on with the medical staff on the field.

"We had a look at half time and he wasn't right so we made that switch.

"It's difficult to say about Great Britain. You'd have to ask Wayne (Bennett, Great Britain head coach) and his medical staff.

"Once we get the scans over the next couple of days, we'll know more about what grade it is and we'll go from there.

"Hopefully it's nothing too serious."

Price confirmed there were no injuries to Jason Clark and Declan Patton and that the decision to replace both was tactical.
