Playmaker Ian Watson has been ruled out for the rest of the season, prompting suggestions McCormack may make a move in the loan market.
But he said: “We’re quite happy to go with what we’ve got this week. We’ve still got a week to play with on the signing deadline, but I’m happy with where we are.”
Lions can wrap up the Co-operative Championship One title – and with it automatic promotion – with a win on Thursday.
McCormack said: “It’s a big game, but only because it’s our next game. Both teams know the importance of this match, but our focus all year has been week-to-week, and there’s no difference with this game. If the last meeting between the sides is anything to go by, this should be a cracker.”
On Keighley, McCormack added: “They’ve got experienced players in key positions. Jason Demetriou is playing well, and Dave Halley has been a good introduction to their squad. We know they’re a dangerous team.”
Cougars coach Demetriou expects to travel to The Willows without Ryan Benjafield (back) and James Haythornthwaite (hip).
Demetriou said: “We’re still in with a chance of finishing first, but if we don’t win this game then the title is Swinton’s.
“The important thing if we do win is that it opens a gap between ourselves and the teams around us chasing second place.”
