Keith Lulia is poised to make his Bulls debut against Wigan on Sunday after Adrian Purtell was ruled out for six weeks.

Purtell tore his pectoral muscle during last weekend’s victory at Castleford and a specialist in Manchester yesterday revealed the extent of the injury.

Fellow centre Lulia has been working towards full fitness after a hamstring injury and may come straight into the side to face Wigan.

Meanwhile, James Donaldson will see a specialist on Monday to discover the extent of the knee injury he sustained against Castleford.
