Manchester United manager David Moyes has calmed concerns over the fitness of defender Nemanja Vidic.
The 32-year-old suffered a blow to the head during United's 1-0 win over Arsenal a fortnight ago, resulting in the centre-back being taken off the field.
"Concussion is something which you do need to rest," Moyes said in a press conference. "He's had his rest and we'll bring him back and hopefully he'll be fine. It's not a serious injury."
United will go up against Cardiff City in South Wales on Sunday.
