Leon Pryce has admitted the uncertainty over his future has had an impact on him this season.

Great Britain international Pryce has denied having agreed terms with St Helens from next season but admits the uncertainty over a new contract has been tough to deal with.

"It does affect people," said Pryce. "It's the first time in my career that I've been out of contract while I've been playing during the season and I think it's the same for the other players who are out of contract.

"No matter what anybody says, it does affect you. It might not playing-wise but it can do mentally. When you are at home and you should be relaxing you can be thinking about it. Or sometimes you can try a bit too hard and then get frustrated because you want to prove your point, that you really want to be here.

"There are loads of different ways it can affect you so you just have to try to handle it as best you can."

The Bulls began the season with six key players coming to the end of their current contracts. Of the six, only Lesley Vainikolo has agreed a new deal, signing a four-year extension early in the season.

Last year's record try-scorer Vainikolo was always the top target but the ongoing battle to keep skipper Jamie Peacock has impacted on negotiations with the likes of Jamie Langley and Lee Radford, while Stuart Reardon has been the subject of repeated big-money offers from Warrington Wolves.

Bradford-born Pryce made an unimpressive return from a three-match ban at Wakefield on Sunday, leading some at the club to question his commitment.

However, he insisted his heart was still in playing for the Bulls.

"I am always excited to play for Bradford and I am always eager and wanting to do well.

"With us not having the best of seasons, we need to kick on and for everybody to be sharp and enthusiastic and wanting to play so we don't finish any lower than we are at the moment."

Meanwhile, Bulls football manager Stuart Duffy has denied the club are interested in New Zealand Warriors forward Karl Temata. The 27-year prop or back-rower hails from Robbie Paul's home town of Tokoroa and has Cook Island ancestry, which means he would not count on the club's overseas quota.

However, Duffy categorically denied Temata was a target: "As usual we are linked with just about every player going at this time of year but there is nothing in it."

Leeds Rhinos legal action against Iestyn Harris and the Bulls began yesterday, with a pre-trial hearing expected to conclude today.

The Bulls Under-21 academy side take on Warrington at Odsal tonight (7.30).
