The 24-year-old left St Helens at the end of last season to sign a three-year deal with the Vikings, but was one of three Widnes players suspended for a breach of club discipline in February.

But while Simon Finnigan and Hep Cahill served one-match bans, Moore was absent for a month as he recovered from a broken jaw.

The Vikings have not disclosed a reason for Moore's immediate departure.

"By mutual agreement, Scott Moore will leave Widnes Vikings with immediate effect," read a Widnes statement.

"The club will not be making any further comment on this matter."

News of Moore's departure comes just 48 hours before Widnes play his former club in the fourth round of the Carnegie Challenge Cup.

Potential

Moore, who played in the Vikings' 38-4 home defeat by Bradford on Monday, made his Super League debut for hometown club St Helens at the age of just 16.

But he was third choice hooker behind Keiron Cunningham and James Roby and spent the 2008 season on loan at Castleford before moving to Huddersfield for 2009.

It was during his spell with the Giants that Moore began to fulfill his potential, appearing in a Challenge Cup final at Wembley, being included in the Super League Dream Team and making his England debut against France.

He returned to St Helens for the start of the 2010 season but moved onto Widnes at the end of last year in a bid to secure regular first-team football and win back his England spot.

Moore has never been far from controversy. He was suspended by Huddersfield in 2009 after missing training to attend an awards night in London with actor Micky Rourke and was last season dropped by St Helens after being arrested on suspicion of drink-driving.
