Rugby Inside Line has reported that fly-half Stephen Myler has been in advanced talks with Sale Sharks over the last few days.
The 33-year-old rugby league convert has put in 12 years' service for Saints since arriving from Salford in 2006 but will leave Franklin's Gardens in the summer.

Myler, third on the Premiership's all-time list of scorers with 1,667 points, went past 300 games for Saints earlier this season - including his man of the match performance in the 2014 final.
Clubs that have also been linked with the one-cap England international have been Bath, Connacht and the French Pro D2.
