World Cup 2019: Australia drafts in Matthew Wade and Mitchell Marsh as cover

Matthew Wade and Mitchell Marsh are waiting in the wings as Australia seeks fitness updates on Usman Khawaja and Marcus Stoinis.

Australia all-rounder Mitchell Marsh has played 53 ODIs.

Australia has drafted in Matthew Wade and Mitchell Marsh as cover as it waits to learn the full extent of injuries to Usman Khawaja and Marcus Stoinis ahead of the World Cup semifinals.

Khawaja sustained a hamstring injury in Australia's defeat to South Africa in Manchester on Saturday and his chances of playing against England at Edgbaston on Thursday appear slim. Captain Aaron Finch was slightly more optimistic Stoinis' side problem was not as severe when addressing the injuries at a post-match news conference.

But Australia is leaving nothing to chance, with wicketkeeper-batsman Wade and all-rounder Marsh brought across from its A team, which begins a four-day match with Sussex on Sunday.

Marsh was also brought into the fold earlier in the tournament when Stoinis sustained a side strain against India, but he recovered to face Bangladesh. Khawaja and Stoinis are set to undergo scans on their injuries on Sunday.
