What the DRS protocol says
The captain may consult with the bowler and other fielders, and the two batsmen may consult with each other prior to deciding whether to request a Player Review. Under no circumstances is any player permitted to query an umpire about any aspect of a decision before deciding on whether or not to request a Player Review. If the on-field umpires believe that the captain or either batsman has received direct or indirect input emanating other than from the players on the field, then they may at their discretion decline the request for a Player Review. In particular, signals from the dressing room must not be given.
