Davidson says injury not fully healed

(GMM) Anthony Davidson says he has not fully recovered from the back injury that left him in hospital after the Australian GP last month.

The Super Aguri rookie jarred his back in a clash with Adrian Sutil in Melbourne but soldiered on despite severe pain to finish a grand prix for the first time.

Davidson, 27, told reporters at Sepang on Thursday that he had injured a muscle connecting a rib with his spine, and spent the next ten hours in hospital.

"It's still not 100 per cent," Davidson, who nonetheless tested at the Malaysian circuit last week, said at Sepang.

"I can still feel it, but I could still drive with it so it's not going to be a problem here."
