Bradford & Bingley must stay on the right side of a difficult balancing act tomorrow at Wagon Lane.

They know that not only must they defeat National League Three North champions Halifax - a hard enough job in itself as they haven't lost all season in the league - but also collect the bonus point for four tries.

Anything short of five points will ruin any chance the Bees have of reaching the play-offs against the runners-up from National League Three South.

But even if the Bees were to collect what they want against the men from Ovenden Park, they would need to do the same again a week tomorrow at their main play-off rivals, second-placed Macclesfield.

Bees coach Geoff Wappett is only too aware of the thin line his side are treading, and said: "It is vital that we don't try and win the game in ten minutes.

"We need to rely on Bloues Volschenk and Tom Rhodes to use their experience and try and maintain discipline throughout the side. We still need to lay a solid foundation."

As for what effect Halifax having already won the league will have, Wappett said: "It can go two ways.

"It could take the edge off Halifax's performance as they know they have achieved their objective or they could play with freedom as they know the pressure is off."

The main injury doubt for the Bees is scrum half Matt Rhodes (elbow), who went off early in the Bees' Yorkshire Cup defeat at Wharfedale on Wednesday night.

Wibsey have half-backs Karl Walker and Andy Todd, full back Richard Burton and flanker Tim Bull back for their much-delayed Yorkshire Silver Trophy tie at home to Richmondshire.

And Yorkshire are bidding to reach the semi-finals of the Under-20 County Champion-ship by defeating Warwick-shire at Otley (2.15).
