Halifax have lost a fourth hooker to injury in five games after Connor Robinson broke his hand in last weekend’s 12-10 home defeat by Toulouse.
Robinson, the former Hull KR player, had started the season at full back, but returned to his more traditional number nine role against the French side.
But he has now joined Brandon Moore (broken hand) and on loan Huddersfield player Adam O’Brien (shoulder) on the long term injury list.
Fax boss Richard Marshall had already spent two weeks without the experienced Ben Kaye because of a shoulder problem.
Marshall has named the Salford hooker or half back Josh Wood in his squad for Sunday’s game against London at the Shay (3.0) along with Red Devils prop Ryan Lannon and threequarter Jake Bibby.
All three players have featured in Super League this season.
“Connor has broken his scaphoid, so he’ll be in pot for four weeks,” said Marshall.
“It’s only a hairline fracture, so it doesn’t need an operation, but we’re still probably looking at six weeks.
“We’re not having much luck in that position at the moment.
“We’ll need to be good on Sunday against a very talented London team.
“They’ve a better side than they had last season, when they gave us a good hiding, and they gave Bradford a good hiding last weekend.
“Our kicking game and discipline needs to be a lot better than it was against Toulouse, but we’re not there to make up the numbers.
“It’s a game that’s important and we want to win it.”
Fax Hall of Fame member Ronnie James, the Welsh full back who scored more than 2,000 points for the Thrum Hallers between 1961 and 1972, has died.
James’ funeral will take place at Park Wood Crematorium, Brighouse on Monday, March 20 at 10.30am.
