Manchester United manager Erik ten Hag criticised the inconsistency of Premier League referees after Casemiro was sent off for the second time in as many months.
Casemiro was shown a yellow card for an overzealous tackle on Southampton midfielder Carlos Alcaraz in the 32nd minute of United's goalless draw, but referee Anthony Taylor was advised to consult the monitor for a replay and he retrospectively dismissed the Brazilian.
The 31-year-old will serve a four-match suspension as he had already been sent off this season against Crystal Palace and it will take the total number of games Casemiro has been banned for up to eight.
