Football's lawmaking body discussed the introduction of kick-ins at a recent meeting.
The annual general meeting of the Ifab took place on Monday.
There were no plans to trial kick-ins at this time.
The idea was included in a number of new proposals last year.
The kick-in option was removed in 1863 and throw-ins have been used ever since.
The two biggest time-wasters are throw-ins and free-kicks.
The goal is to make the game more spectacular and quicker, and maybe with throw-ins you could play with your feet in a limit of five seconds.
It needs to be tested and accepted by the Ifab.
The VAR technology could be ready in time for the tournament.
Pierluigi Collina, chairman of the governing body's referees committee, is confident that a decision can be made before the tournament starts.
The automated ball detection technology will continue to be used in trials.
The laws of the game have been changed to include the use of five substitute players.
Despite calls for temporary concussion substitution to be introduced, the trial of additional permanent concussion substitute has been extended until August of next year.
The trial only allowed for permanent concussion substitution in December 2020, despite the Professional Footballers' Association's call for temporary substitution to be included in the testing.
If a player suffers a head injury, the rule allows for a permanent substitution to be made.
Ifab said that members agreed that the trials should continue to focus on permanently removing any player with a concussion to ensure that they don't continue taking part.
Further education is required to make sure the trial protocols are applied correctly.
Dawn Astle, the daughter of Jeff Astle, who died of a brain condition linked to heading footballs, said prior to Ifab's latest decision that players are being put at risk.
Body cameras worn by referees could be used to improve the safety of officials.
The treatment of officials at grassroots level could cause many to leave the sport for good according to research.
Following calls from referees and league administrators, the Football Association proposed a body camera pilot to Ifab.
May 2020 was when the use of five substitute was first introduced.
The rule will not be used in the 2020-21 season, but top-flight clubs will return to five subs from the start of the 2022-23 season.
The number of named subs in the matchday squad should be increased from 12 to 15.
