World Cup: 'Leave it to VAR' linesmen told not to flag for tight offsides

Supporters at the tournament in Russia will be shown clips of the passage of play that was under revision but only once the referee has made his decision and play has restarted.

Pierluigi Collina, the chairman of Fifa’s referees committee, said the problems with lengthy delays during trials had been ironed out. The Italian also said assistant referees had been advised to keep their flag down for tight offside calls and to leave it to VAR to decide.
