Ireland's John Lacey will referee his first ever RBS 6 Nations while Alain Rolland is also included in the Elite Panel in what is his last season.
The incident was caught on television cameras but missed by match officials.
He will appear before a disciplinary panel on Wednesday and if found guilty, a ban of more than one match would rule Philip out of Edinburgh's European Cup quarter-final against Toulouse on April 10.
Edinburgh have already lost the injured No 8 Simon Taylor for up to nine months and Scotland assistant coach Todd Blackadder was considering a return. "I'd have to think it through because you have to know when to go, but I would say it's not out of the question," the 32-year-old former New Zealand skipper said.
