DEFENDERS Paul Scott and David Mirfin are on standby to step in as Town target a sixth consecutive home win against bottom club Carlisle United tomorrow (3.00).
Manager Peter Jackson rates ankle-injury victim Nathan Clarke no more than 50-50 for the visit of Paul Simpson's strugglers, who have never before played at the McAlpine Stadium.
So Scott and Mirfin will wait for a call to replace the 19-year-old as Town bid to extend an impressive defensive record in front of their own fans this season and chalk up a much-needed victory before they go into the hat for the FA Cup first round draw at 5.05pm.
It is six hours since Town even conceded a goal at the McAlpine and, after away defeats to Lincoln and Yeovil, Jackson is determined to extend that blank to seven and a half hours and gain three points.
Carlisle are captained by Chris Billy, who scored Town's Wembley play-off final winner in 1995, and Jackson hopes the McAlpine gives him a warm reception before getting fully behind Town's bid.
"Anyone who looks at the table and thinks this is going to be a walkover is very much mistaken and we will need to be firing on all cylinders to win tomorrow," said Jackson, who will watch Carling Cup opponents Reading in action at Sheffield United tonight.
"We desperately want to keep our home form buzzing and, if we could transport our McAlpine defensive displays away from home, we would be right up there in the table.
"Like every club this season, Carlisle will raise their game against us, so we need the fans right behind us and we need to get back to our best passing and movement in what will be a big, big test."
Jackson will bring his players in for training on Sunday to prepare for Tuesday's trip to the Madejski Stadium. He said: "The lads know they let themselves down at Yeovil and I detect they want to put that right at home tomorrow."
BBC pundit John Motson will mark Kick Racism Out of Football Day at the McAlpine by watching the match against a Carlisle side who've won just one in nine. He will make a presentation on behalf of the Supporters Trust.
Cut-price Reading tickets are on sale at the McAlpine until 5pm on Monday.
