Chairman Chris Caisley is calling on fans to get behind the Bulls for what is shaping up to be the toughest 11 days of the season.

Friday's home match against high-flying Hull FC will be followed by the visit of Leeds next Thursday, before the Bulls end their Easter programme with a trip to St Helens on Monday.

With a tough trip to Warrington to follow the relative respite of a Challenge Cup tie at Featherstone, the next month will go a long way to determining the outcome of the club's season.

"We have four big games coming up. Two of them are at home and we have got to be looking at taking the points from those," said Caisley.

As well as the Super League points at stake, the club are also desperate to cash in on the plumb ties. The revamped Super League draw means there will be no bumper end to the season, when the top six clubs have traditionally faced each other as the clamour for play-off places hots up.

Instead, Hull will be the only top-six club to visit Odsal in the last three months of the season.

"These two home games are massive for us," said Caisley. "They will be good games, top games to watch. Unfortunately, once we get to the second half of the season we don't have many of these fixtures so we need to do our best to get the big crowds early on.

"After a difficult start we are starting to turn things around and these games will be a real test of how far we have gone in the right direction.

"Hull are playing attractive football. They have got Steve Kearney back and Richard Horne, so they are going to be difficult to beat and we need all the support we can get."

Negotiations with star winger Lesley Vainikolo had been progressing well despite interest from rugby union club Gloucester, revealed Caisley.

"We are fairly optimistic we can retain his services beyond this year and, obviously, if we can do that it will be a massive boost for the club."
