Sheens had said that if the Tigers did not make the finals last year he would not seek an extension beyond this year, the last of his current deal.
The Tigers made the finals and went as far as the grand-final qualifier, when they lost by a point to eventual premiers St George Illawarra, and now the club is seeking to extend his stay to more than a decade.
It is clear that if Sheens and the Tigers can reach an agreement on the terms of a new deal, he will be staying, and it is no surprise the club has decided to move early on him since there is the potential for several coaching jobs to open up at the end of the season.
Sheens would be in demand if he was a free agent then.
This will be the ninth year for Sheens at the Tigers, equalling his previous longest stay at a club – at the Canberra Raiders, from 1988-96.
