Bradford face an anxious wait over the injury suffered to half-back Luke Gale, who will see a consultant in the next 48 hours.
Gale, 24, suffered ankle ligament damage in the 54-16 defeat against Wigan on Sunday, when team-mate Elliott Whitehead fell on him whilst making a tackle.
A close season signing from Harlequins, Gale was playing in just his third match for the Bulls.
X-rays showed no break, but he could now face an operation to repair the ligament damage, which was uncovered when swelling on his ankle had gone down.
