The scope of the video assistant referee in the Premier League might be expanded in the future to include decisions on yellow cards and the awarding of corners, says Howard Webb.
Referees' chief Webb says the game's law-makers, the International Football Association Board (Ifab), is reviewing how VAR operates and he is "open to discussions" about other uses.
VAR, which has operated in the Premier League since the 2019-20 season, can currently only intervene in what are perceived as match-changing decisions - goals, straight red cards, penalties and mistaken identity.
"There will definitely be discussions around possible extensions," Webb told BBC Sport.
