Chris Ashton, who will join Toulon at the end of the season, is back in the Saracens match squad to face Newcastle at Allianz Park tomorrow after serving a 13-week ban for biting.

Ashton, who was found guilty of biting Northampton’s Alex Waller in September, will start on the replacements’ bench.

The wing’s latest disciplinary ban convinced the 29-year-old that he had to leave English rugby where he believes he has been unfairly treated, even though it will end his hopes of an international recall under Eddie Jones.

Ashton, who scored 19 tries in 39 Tests, joined Sarries in 2012 and has won two Premiership titles and the Champions Cup.

Harlequins are expecting a bumper crowd at Twickenham for their Big Game against Gloucester on Tuesday.
