The International Football Association Board (IFAB) has released a Circular regarding Law 11 - Offsides.
Following requests from a number of football associations and confederations regarding offside, the IFAB would like to provide additional clarification and/or guidance relating to the definition of the offside offence of 'interfering with an opponent' and also to the definition of 'save' in the context of offside (Laws of the Game).
The OSA has been requested by FIFA and directly through the CSA Referee Committee, to pass this Circular along to all of our match officials.
