The ex-Saracens and Northampton player, 32, joined Sale from French Top 14 side Toulon in July 2018.

Ashton scored 20 tries in 44 England Tests, winning his last international cap in February last year.

In January, he told BBC Sport's Rugby Union Weekly Podcast he is aiming for a record 100 Premiership tries before his club career is over.

His most recent try in a victory at Exeter on 25 January took his Premiership tally to 86 - six behind all-time Premiership top try-scorer Tom Varndell.
