Manchester United boss Sir Alex Ferguson insists Rio Ferdinand's latest injury setback is no major concern.

Ferdinand's calf injury is expected to clear in time to face Marseille in the Champions League in 10 days' time, with Ferguson insisting that the problem is not due to a recurrence of previous back problems.

He said: "It could have happened to anyone. It's nothing to do with his back. That was our main concern.

"It'll just be a couple of weeks out, but you have to remember he's been in first-team football since he was 17 years old. That's a long time so he'll pick up little strains like a lot of players do. I'm sure this isn't a long-term thing."
