The Bulls have confirmed Patrick Ah Van will leave the club at the end of the season.

As reported in the Telegraph & Argus last week, the Kiwi three-quarter has not been offered a new deal for 2012.

Ah Van arrived from New Zealand Warriors on a one-year deal last winter but, despite some encouraging early performances, has struggled to find form of late.

The 23-year-old has signed a two-year deal with Super League newcomers Widnes Vikings.
