Tuilagi will face a RFU disciplinary hearing in London on Wednesday, his 20th birthday.
He has been reported by independent citing officer Alan Mansell for punching Ashton during the first half of Leicester's 11-3 victory at Welford Road.
Tuilagi, one of England's brightest midfield candidates and a World Cup squad contender later this year, is set to miss the Aviva Premiership final against Saracens at Twickenham on May 28 if he is banned, and possibly England Saxons' Churchill Cup campaign next month.
