The Premier League is to urgently review VAR calls in Saturday's matches involving West Ham and Newcastle United with PGMOL, the official referees organisation.
Incidents involving the use of video technology in West Ham's 2-1 loss at Chelsea, and the goalless draw between the Magpies and Crystal Palace will be looked at.
Both games saw goals chalked off, causing significant controversy with players, managers, pundits, and fans.
VAR was also integral to the results of several other matches on Saturday, but the Premier League and the Professional Game Match Officials Limited - PGMOL - are only looking into the overturned goals at Stamford Bridge and St James' Park.
