FIFA's lawmakers meet on Saturday to discuss changes to soccer's rulebook including extra referees, sin-bins for yellow card offences and increasing the number of substitutions during a match.

The International Football Association Board (IFAB) - which sets the rules for the world's most popular sport - will assess whether extra linesmen monitoring penalty areas at the end of each pitch can help alert referees to fouls or diving, while avoiding the need to introduce potentially disruptive video replays.

The IFAB will also consider a plan to extend halftime from 15 to 20 minutes and a clarification of the wording of the offside law.
