FIFA's lawmakers will shortly meet 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, report Reuters. The International Football Association Board (IFAB) 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.

But the IFAB - made up of the four British associations and four representatives from FIFA - will look at the merits of introducing rugby's sin-bin whereby a player booked for a foul is sent to sit on the sidelines for a set amount of time.

Another proposal being considered, from the Scottish FA, is to increase the number of substitutes allowed from three to four when a match goes to extra-time.

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.

The new wording seeks to erase any doubt that even if the defender leaves the field, he is still "active" as far as offside is concerned.

It would read: "Any defending player leaving the field of play for any reason without the referee's permission shall, until he returns to the field ... be considered to be on his own goalline or touchline for the purposes of offside."
