Warrington have confirmed that back-rower Ben Currie has aggravated an old knee injury, but they are hopeful he will return in March.
Currie, 23, left the field inside the first quarter during the win over Wigan on Friday night and there were fears it may be serious.
He sat out a large chunk of the 2017 season after sustaining an ACL injury against Wigan in September 2016, and was restricted to just four appearances for the Wolves last year, before turning out six times for England during the World Cup.
A Warrington club statement said: “The recent scan has shown that Ben Currie aggravated an old knee injury.
“It’s nothing too serious, it’s a matter of getting the swelling down followed by rehab.
“It’s hoped he’ll be back within the next 4 weeks.”
Warrington take in home games against St Helens, Wakefield and Widnes, as well as trips to Hull and Catalans during March.
