Harrison is at the centre of speculation linking him with a switch to The Shay for 2012, but his immediate focus is on steering Batley to the Co-operative Championship Grand Final.
Harrison said: “I’m confident we can beat anyone. We’ve a very competitive squad and motivation for big games is never a problem.”
Halifax caretaker coach Damian Ball will check on the fitness of Makali Aizue (ankle) and Steve Bannister (suspected broken thumb) after the pair picked up knocks during Sunday’s 32-24 win at Hunslet Hawks.
Jim Gannon is definitely ruled out after being handed a one match suspension by the RFL’s disciplinary committee.
Halifax trailed 20-6 at half time against Hunslet, but produced a much better second-half performance to secure the points – and some confidence – ahead of Thursday’s clash.
Ball said: “The way we’re starting games is something we need to address. We need a massive start in this crucial game against Batley.
“The second half performance (against Hunslet) is what we needed going into a big game.”
On Batley, Ball added: “They’re a bit of a bogey team for us this year, but we know what to expect.
“Karl gets his troops up really well, and the key for us is to out-enthuse them. There’s no question it’s a difficult game, but if we prepare well then we’ve got a chance.
“We’ve got some threats and we’ve got some tricks up our sleeve, but it’s going to be tough. We’ve got to make sure we play smart.”
