Grewcock is acccused of punching and acting 'contrary to good sportsmanship' during the match which saw his side lose by 27-10 at the Recreation Ground.
The 30-year-old will appear before a Rugby Football Union disciplinary panel at Gatwick on Tuesday, March 25 and if found guilty and given a ban would miss England's much-anticipated trip to Dublin which takes place five days later.
While he has made the starting line-up just once during England's current Six Nations campaign, against Italy when skipper Martin Johnson was sidelined through injury, Grewcock has been an ever-present in Clive Woodward's match-day squads so far.
A ban to one of their most influential players would also be a major blow for Bath as they attempt to stave off the threat of relegation at the bottom of the Zurich Premiership table.
Grewcock holds the dubious distinction of being only the second ever England rugby to be sent off during an international. He was given his marching orders against the All Blacks on England's tour of New Zealand in 1998 for excessive use of the boot.
