Webb has always been a superb referee when officiating City games and could be seen as somewhat of a lucky ref for City.
He was in charge of the play off semi final win over Bristol City, the play off final win over QPR as well as the win against Forest.
Also this season he reffed Burnley v City (1 - 1) and Wimbledon v City (a 1 - 0 win for Cardiff).
His only other Cardiff game was a 0 - 0 draw at Notts County in November 2001.
The assistants are due to be Tony Green of Leicestershire and Andrew Butler of Lancashire.
