Manchester United boss Sir Alex Ferguson has played down injury concerns surrounding Wayne Rooney.

The striker hobbled out of his side's 1-1 draw with Blackburn on Saturday.

Rooney appeared to suffer a hip injury in the second half, and was in some discomfort before finally being taken off late in the game.

There were obvious fears that Rooney would miss out on the first leg of the Champions League clash with Barca, but Ferguson remained optimistic.

"Wayne got a knock on the hip but I'm sure it won't keep him out of Wednesday night's match," said Ferguson. "Sometimes when you get a kick on the bone it can be very sore at the time but I expect he'll recover."
