Mark Molesley says the loss of left-back Nathan Ralph is a bitter blow.
Ralph came off in the early stages of the defeat to Salford City and a scan result earlier this week confirmed he has suffered cruciate ligament damage which will rule him out of action for the remainder of the season.
Molesley said: "It’s a bitter blow that we’ve lost Nathan for the season.
"He joins Lewis Gard with a similar injury as well who we lost two weeks previous so it’s a tough one to take.
"To say we’ve been unlucky with injuries since we’ve been here would be an understatement.
"We’re trying to get some players up to speed as we speak and we’ve picked up a couple of freak nasty ones as well.
"I’m bitterly disappointed for them as well because they’re two really good guys who we’ve enjoyed working with and can’t wait to have them back training with us in the future."
Everyone at Blues wishes Nathan and Lewis a speedy recovery.
