Football Association clarify Hessenthaler's off / on

Last updated : 15 September 2003 By Michael Morris
There was many a question raised as to the legality of his actions. He also received a yellow card in the second half, another would have seen him sent off twice in the same game.

The FA have cleared up the matter saying he was allowed to come back on the pitch

statement from the FA Website
"This was possible due to the fact that he was sent from the dug-out for a technical issue, rather than a more serious offence such as abusive language or violent conduct which could be charged under The FA's disciplinary regulations"
