Lindsey Vonn has had three operations since Sunday's crash

Lindsey Vonn says she is "making progress" after having a successful third surgery on the broken leg she sustained in a crash at the Winter Olympics on Sunday.

The American great was racing just nine days after rupturing ligaments in her left knee when she struck a gate 13 seconds into her downhill run in Cortina.

She was airlifted off the piste and taken to hospital in Treviso, where she was diagnosed with a "complex tibia fracture" in her left leg.

"I had my third surgery today and it was successful," she wrote in a post on Instagram.
