Vanishing Spray In Action
Vanishing spray will be used for the first time in a Blackpool league match when Millwall visit Bloomfield Road on Saturday.
Referees had access to the spray for third round of the FA Cup over the weekend, and the Football League announced in November that it would be used from January 1 in league action too.
Used to good effect in the World Cup, vanishing spray was trialled in this year's Johnstone's Paint Trophy and will now be a mainstay in English football.
