James Hall, Taiasina Tu'ifua and Rob Vickers have all been cited by the Rugby Football Union after Newcastle's 9-9 draw with Harlequins last Friday.
Hall, 25, was cited for kicking an opponent, Tu'ifua, 27, for a dangerous tackle and 30-year-old Vickers - who picked up a yellow card - for striking.
The Falcons trio will have their cases heard in Durham on Monday, 19 March.
Quins coach Conor O'Shea had criticised Falcons' approach in his post-match comments at Kingston Park.
"The line is drawn at punches in the face, boots in the face and short-arm tackles," he said.
In response Falcons coach Gary Gold replied: "Was it my instructions to go over the top? Certainly not.
"I would never tell my players to do that. I don't condone any sort of dirty play, but I do ask my players to front up.
"I'm not happy with the ill-discipline we showed at times."
