"I got six starts last season and I can't face the prospect of the reserves, going to a place like Widnes rugby ground, and then not having a decent club to go to in the summer.
"I've got no problems whatsoever with the gaffer or the coaching staff but it's time to move on.
"I know Walsall have asked about me and they do appeal to me but it is in the hands of the gaffer and the board."
