Mansaram was protesting against Stretton's decision to award Chesterfield a contraversial late penalty. David Reeves scored to complete his hat-trick and make the game 4-4.
Early thoughts indicated that Mansaram would pick up a three game ban, however the club have now had comfirmation from the Football League and a two match ban is to be served.
The young striker will miss the Easter double header against QPR and Blackpool.
