Sorry but that's complete cock. See following extracts from the official FA handbook:
"A player who is dismissed from the Field of Play for denying a goal or an obvious
goalscoring opportunity by physical means or by handling the ball, will be suspended
automatically from all Non-First Team Matches commencing on the 14th day following
the match in which he was sent off, until such time as THE CLUB has completed one
match in the competition as decided by The Football Association."
and
"E3 CHARGE FOLLOWING A DISMISSAL WHERE STANDARD PUNISHMENT
CLEARLY INSUFFICIENT
(a) All players dismissed from the Field of Play shall be subject to at least a one match
suspension, save only for where a successful claim for wrongful dismissal is brought.
(b) A Player may be charged by The Association under Rule E3 in relation to certain
on-field incidents for which the Player was dismissed, pursuant to Regulation 8(i)
below, where The Association is satisfied that the standard punishment that would
otherwise apply following the dismissal is clearly insufficient.
(c) Charges may be brought under this Regulation only for on-field offences which have
resulted in a sending off under Law 12(1) (violent conduct), Law 12(2) (serious foul
play) or Law 12(3) (spitting)."
