Canaries boss Paul Lambert has admitted an FA charge of improper conduct.

The case will be heard by an FA Regulatory Commission by September 11 - and Lambert could be given a touchline ban.

Lambert was charged following an incident on the opening game of the season, when he was manager of Colchester United.

The Scot Lambert was frustrated at the performance of referee Russell Booth during the match against Yeovil - Colchester won 2-1 but the official awarded the visitors a late free-kick from which Ryan Mason scored.

Lambert said afterwards he needed "an abacus" to count the referee's poor decisions.

"I'm bewildered why the referee refereed the game, so there you are," he said at the time.

"I needed an abacus to count the (bad) decisions that he made and I never had one in the dugout. I'm delighted we won. I'm not giving the officials any credence."

The FA will take into account Lambert's previous disciplinary history in making their decision - the best he can hope for is a warning or a fine, the worst a touchline ban.
