Manchester United manager Alex Ferguson has criticized Rio Ferdinand for not wearing a T-shirt during an anti-racism campaign, calling the decision ''embarrassing.''
Ferguson hinted at disciplinary action for the defender.
Players across England donned the T-shirts during the warm-up before league matches on Saturday as part of the Kick It Out campaign against racial abuse.
However, Ferdinand didn't wear the shirt before United's 4-2 win over Stoke in protest for the campaign group's perceived lack of action during recent high-profile racism cases.
Chelsea's John Terry was recently banned for four matches for racially abusing Ferdinand's brother, Anton, during a league game. Chelsea chairman Bruce Buck said Saturday Terry will remain the club's captain.
In an interview with United's in-house television channel, Ferguson adds Rio Ferdinand's action ''lets us down.''
