The club confirmed that Diamond faces two charges of conduct prejudicial to the interests of the union and/or the game, in contravention of rule 5.12 of the RFU's rulebook, stemming from a touchline incident during September 23's Aviva Premiership clash with Northampton Saints.
Sharks chief executive Mick Hogan said: "We have already conducted an internal investigation into the incident which occurred on the touchline during the first half of the game.
"Following the investigation, Steve has accepted a club sanction for his behaviour. The RFU have been informed of the sanction, that will otherwise remain private and confidential. The club and Steve have no further comment until the hearing on Tuesday."
