Warrington halfback Chris Sandow has suffered a grade two hamstring tear and could be out of action for between two to eight weeks.
Sandow suffered the injury against Wigan on Friday. A grade two tear usually takes between a fortnight and up to two months to heal, depending on the severity.
Hamstrings are notoriously unpredictable injuries to recover from.
Warrington head coach Tony Smith said the playmaker is seeing a consultant before he will put a timeframe on his return.
“He’s had his scans and he has a Grade Two hamstring tear, he’s going to see one of the leading hamstring consultants this evening,” Smith told The Warrington Guardian.
“We’ll get his viewpoints before jumping to estimations about how long he will be out. We’re getting him to the right people and getting him back as quickly as possible is the next challenge.”
