The NSW Origin forward was hit Monday with a grade two charge by the NRL match review committee for making unnecessary contact with Laffranchi's face in the 67th minute of Saturday's game on the Gold Coast.
Gallen re-opened a nasty wound on the heavily bandaged head of Laffranchi during the incident, forcing the forward from the field and afterwards prompting Titans captain Luke Bailey to call it a "grubby" act.
The charge usually carries just a two match ban, but because of previous offences, Gallen will be facing a three-match ban with an early guilty plea, and four if he defends the charge at the judiciary and loses.
St George Illawarra forward Jarrod Saffy, meanwhile, has had a contrary conduct case referred straight to the judiciary after Canberra halfback Todd Carney alleged the Dragon bit him late in the first half of their match on Saturday.
Three other players have been charged, but Roosters five-eighth Braith Anasta sidestepped any judiciary drama ahead of Friday's grudge match against the Bulldogs with no charge laid over his high shot on Melbourne winger Steve Turner.
Brisbane's Reece Robinson and North Queensland's Travis Burns were both charged with dangerous throws.
Robinson can escape suspension with an early plea, while Burns is facing a one-match ban with an early plea - and two if fights the charge and is found guilty - because of previous offences.
Melbourne veteran Matt Geyer has been charged with contrary conduct for making unnecessary face contact, but will avoid a ban with an early plea.Like
