Halifax coach Karl Harrison is calling for more composure in his team after they drew 22-22 with Batley Bulldogs.
Harrison said: “We were cruising, but we love a good self-destruct at times at Halifax. It was extremely disappointing.
“If we had good game-management we’d have won comfortably.”
And Harrison insists his side will need to be at full power to beat Whitehaven in Sunday’s Kingstone Press Championship fixture.
He said: “Anybody can beat anybody at this level. If you turn up a little bit soft, you’ll get beat.”
Whitehaven coach Dave Woods could include Samir Tahraoui, who has recovered from a recent ankle problem.
Woods watched as Whitehaven won 40-34 against Dewsbury Rams last week, but says more concentration is needed if his side is to fulfill its potential.
Woods said: “We can’t afford to come up with those little errors, because that’s then letting teams into the game.”
