Reports suggest that Ashton did not require stitches to the cuts on his face, although he was said to be shocked by what is understood to have been an unprovoked attack.
The 25 -year-old will be deeply concerned about the potential ramifications of the incident, regardless of his role, given that he has been caught up in such events before and only recently joined Saracens with the stated aim of having a fresh start.
England head coach Stuart Lancaster has shown in his dealings with the controversial scrum half Danny Care that he is not afraid to suspend players who get caught up in trouble off the field.
Ashton, like all the England squad, was warned about the need for blameless behaviour when Lancaster took over last December.
Negative headlines do appear to follow Ashton around, with his celebratory dive over the try-line understood to infuriate his coaches, and numerous off the field incidents.
Ashton found himself embroiled in an incident in a Dunedin hotel room during last year’s Rugby World Cup which prompted a furious response from the then England manager, Martin Johnson.
Lancaster suspended Danny Care for the entire Six Nations championship after the Harlequins scrum-half was involved in several drink-related incidents, the last of which saw him breathalysed and banned from driving.
