HALIFAX centre Mick Nanyn will have a scan to determine the extent of his knee injury on Friday.
The record-breaking threequarter, who is seventh on the all-time points-scoring list after a prolific career in the Championship, has made just one appearance for Fax, against Keighley on Boxing Day, since his close-season switch from Leigh.
A training ground collision ruled the 29 year old out of the matches against Salford, Leigh and Huddersfield, with the club’s medical staff now suspecting cartilage damage.
“We should know more about Mick after the weekend,” said Fax boss Karl Harrison, who already has a handful of key performers sidelined through injury.
“He’s not been improving as quickly as he should, and I’m told there’s a fair chance he might need an operation of some kind.
“Mick’s spoken to someone about it already; if he’s got a tear in his cartilage, he could be out for around three months.
“If he just needs a standard clean out, it’s probably two to three weeks.
“All we can do for now is wait and see.”
Harrison’s side, who wrapped up their pre-season with last weekend’s 58-6 win over Huddersfield, will train as normal in the run up to their Northern Rail Cup opener at Dewsbury on Sunday week.
“We’re in Monday, Wednesday, Friday this week and the same next,” said the former Great Britain prop.
“We’ll keep the momentum going and keep working hard.”
Fax do have an under 23 friendly against the re-launched North Wales Crusaders in Wrexham on Sunday, although Harrison is not expected to field any of his first team squad.
