Denis Betts has left Widnes Vikings.
The 48-year-old was Super League’s longest-serving coach, having been appointed at the Vikings in 2010.
Under his watch, the club was promoted to Super League in 2012 under the franchising era and guided them through their current Super League tenure.
The Vikings finished seventh in 2016, their highest finish during Betts’ spell. But last year saw them flirt with relegation, and although they survived, they are currently bottom of Super League this term, five points adrift of the top eight.
In a short statement, Widnes said: “The club would like to put on record its thanks for his contribution, for eight seasons.”
Assistant coach Francis Cummins has been placed in temporary charge as the Vikings consider their next move.
