Matildas bombshell as Sam Kerr is spotted wearing ice pack on her calf

Australia have been given a major scare ahead of their World Cup semi-final against England as Sam Kerr was spotted with a heavily strapped right calf on Tuesday.

The Matildas star sported an ice pack on her right calf as he walked back into the team hotel on Tuesday with her teammates  after training.

Kerr, the Matildas captain and all-time leading goalscorer, injured her left calf a day before Australia's tournament opener against the Republic of Ireland last month and  was forced to miss all three group stage games as a result.

The Chelsea forward came off the bench for the last 10 minutes of the 2-0 win over Denmark in the Round of 16 clash and was introduced with 55 minutes gone in the quarter-final against France on Saturday.

Kerr converted one of the spot kicks as the Matildas beat France 7-6 in a penalty shootout to advance to a World Cup semi-final for the first time in their history.

Speaking on Monday, the 29-year-old said she was ‘ready to go’ against France having shrugged off the calf injury she sustained in training before the tournament, but revealed the plan was always to get her fit for the semi-final.

‘When I hurt my calf, the plan was to always to [try to] be ready for a semi-final, the final.

'So I could have [started against France], but who knows what could have happened?

'The girls have been smashing it and absolutely dominating.

‘I was ready to go, but we’ve had a plan this whole tournament and we just had to stick to it.

‘That was part of the plan, to get 20 minutes against Denmark to make me feel better for this game and now with another, what, 65 minutes, I feel better for it and I’ll have more training under my belt.

'So I feel ready to go. I think with everything that’s been going on, the best thing
