“My clear ambition is first to regain my place in the Saracens team and then to regain my place in the England side,” Ashton said in a statement.
“It may seem a long journey back from the despair of last week’s judgement but I will do everything in my power to get back to where, in my heart, I feel I belong.”
Ashton was handed a 10-week suspension earlier this year for making contact with the eye of an opponent during a Champions Cup match, crushing his hopes of a recall to the England squad for this year’s Six Nations.
The former rugby league player maintains his innocence in both incidents.
“I told the disciplinary panel that I did not bite the Northampton prop, just as I had told the panel in January that I did not make contact with the eyes of the Ulster centre,” he added.

“Both panels chose to accept the opposing version of events. I did not agree with either verdict but I must and do accept the sanctions.”
Ashton was not included in England coach Eddie Jones’s 45-man elite player squad which was named last month.
