Grant squared up to Friend after the half-time whistle after seeing two penalty claims turned down and having Ricardo Rocha dismissed for conceding the penalty which led to Darren Bent's 12th-minute opener at Fratton Park.
Grant also ranted after the game about decisions going against his side, but an FA statement confirmed: The charge relates to Grant's behaviour towards referee Kevin Friend at the conclusion of the first half of Portsmouth's match against Sunderland at Fratton Park on February 9.'' Grant has until next Thursday to respond to the charge, which will be heard by March 5.
Friend also dismissed Lee Cattermole and David Meyler for the visitors but Grant felt his side were still on the rough end of the decisions.
Referees are honest but they go with the atmosphere and they also read the papers, so it is easy to do it,'' Grant said after the game.
I cannot fight against the whole world.''
