Giggs forced off against Liverpool due to bug
Sir Alex Ferguson has confirmed Rio Ferdinand missed Manchester United's thrilling 3-2 win over Liverpool due to illness.
Ferdinand was expected to retain his place in the United side for Sunday's game after making his comeback from a knee injury against Rangers in midweek.
However, the centre-half was unable to resume his partnership with new captain Nemanja Vidic for the visit of arch-rivals Liverpool.
Jonny Evans started in Ferdinand's absence while veteran winger Ryan Giggs was substituted late on after also complaining of feeling unwell.
United boss Ferguson is now hoping that a bug will not sweep through his squad ahead of Wednesday's Carling Cup tie at Scunthorpe United.
"He was ill at half-time and was feeling really queasy," Ferguson told Sky Sports regarding Giggs, who went straight down the tunnel after being replaced.
"He had a wee bit of a bug and Rio Ferdinand had it last night also.
"Hopefully it's something that's not going to spread."
