In-form Bulls winger Tevita Vaikona has been ruled out of Sunday's return to Super League action against London Broncos at Valley Parade.

Vaikona limped out of last week's Challenge Cup semi-final win over Warrington Wolves with ankle trouble and needs further time to recover fully.

"Fortunately there is no break," said Bulls coach Brian Noble, "but it is still very sore and he is not going to make it. He should be back for the game at Wakefield on Thursday though."

Noble is making a late check on Aussie back-rower Daniel Gartner who missed the semi-final but he remains a big doubt.

But Lee Gilmour and Lee Radford both reported back for training yesterday after illness and have been named in the squad.

Leon Pryce is favourite to take Vaikona's place on the right flank with Gilmour, who hasn't trained for ten days, likely to have to make do with a place on the bench

"I would have liked to have changed things around but the injuries to Tevita and Daniel restrict us a little and it will be pretty much the same group of players again this week," added Noble.

London have their own injury problems too with former Wigan loose forward Andy Johnson ruled out for six weeks with a shoulder injury. Aussie prop Justin Dooley has been dropped for 'disciplinary reasons' so off-season recruit from Wigan Tony Mestrov will get his first starting berth of the season in the front row. Utility forward Mat Toshack will be elevated to the starting line-up at loose forward.

The Bulls Alliance side, who top the table after winning their first four games, take on London at Odsal tomorrow (2pm). It will be followed by an Academy clash between the two clubs starting at 4pm. The club are also advising that fans purchase tickets in advance for the Easter Monday clash with Wigan at Valley Parade.

"We expect a huge crowd and with a noon kick-off it will ease congestion on matchday considerably," said media manager Stuart Duffy.

The Odsal ticket office will be open on Monday and Tuesday (9am to 5.30pm), Wednesday (9am to 8pm) and Thursday (9am to 6.30pm). It will be closed next Friday, Saturday and Sunday.
