If Warrington's recent record at Knowsley Road is not enough to turn the stomach, then a bout of sickness in the Wolves' camp has made it a queasy preparation for today's meeting with St Helens.
Warrington were forced to cancel training on three consecutive days, with six players and their coach, Paul Cullen, all affected by the virus.
"The guys who were struggling have all come through," Cullen said. Despite Saints' dominance in this fixture,their coach, Ian Millward, is wary.
"Warrington rested two of their best players with this game in mind," he said.
One of those players, Lee Briers, failed a test on a shoulder injury, but Mike Forshaw and Paul Wood return.
