Ferdinand has declared himself finally free of the back injury which has cast a shadow over his preparations for this summer's World Cup finals.
He said: "This latest problem has only been a minor setback. It's just been precautionary, me not playing, to make sure it doesn't get any worse.
"But I'm fine now, no pain, so I'm cool.
"It was decided it was best for me to stay in Manchester and train, rather than with England."
