HALIFAX boss Karl Harrison is waiting to discover whether frontline forwards Sam Barlow and Makali Aizue will need close-season ankle surgery.
Barlow, the Scotland international, saw a specialist earlier this week and is waiting for the results of a scan.
Aizue, the 34 year old Papua New Guinea front rower who is now the club’s oldest player by some distance, is expected to undergo a similar examination in the next few days.
“They’ve both got problems that will potentially need operating on,” said Harrison.
“They’re getting assessed at the moment and that will determine how we deal with them.
“We’ll wait until we have all the information and then make a decision.”
Harrison reported an otherwise healthy squad after last night’s second pre-season training session, and admitted he was pleased with the initial reaction to his new regime.
“It’s gone very well so far,” said the former Great Britain front rower.
“They have all come back in pretty good shape and they’ve really pushed themselves in the testing we’ve done so far.
“It’s been gym based: bench press, squats, rowing machine, that kind of thing, plus a few scientific things that Nigel Halmshaw has brought with him.
“There’s a nice buzz about the place.”
Only three players are currently absent on extended leave: Ireland internationals Paul Handforth and James Haley - although their Wolfhounds teammate Callum Casey is in training - and the Wales forward Ross Divorty.
“They’ll all be back in the next week or so,” said Harrison.
St Helens will be playing at Langtree Park from next season after the developers of their new £20million stadium gained the naming rights.
The 18,000-seater stadium, which was completed last month, is the centrepiece of a major regeneration of a former glassworks near the town centre.
St Helens chairman Eamonn McManus said: “Securing a naming-rights deal was a big part of the new stadium plan and we’re delighted to extend our relationship with Langtree.
“Langtree has done a fantastic job on the stadium and we know that once the stadium fit-out is complete that it’s going to be the best arena in the country to watch rugby league.”
Saints’ first match at their new home will be a pre-season friendly against Widnes on January 20.
St Helens ground-shared with Widnes throughout 2011 after moving out of Knowsley Road, their home for 120 years.
