Manchester United will not appeal against Casemiro's suspension after the midfielder was sent off during Sunday's 0-0 draw with Southampton.
Casemiro was dismissed in the 34th minute having initially been shown a yellow card for his challenge on Carlos Alcaraz, before referee Anthony Taylor upgraded it to a red card following a VAR review.
United have decided not to make an appeal to the Premier League and the midfielder will serve a four-match ban, in games against Fulham, Newcastle, Brentford and Everton, because it was his second red card of the season.
