The Ashes: Tim Paine 'devastated' to hear of Will Pucovski's concussion, backs Marcus Harris to open

The Ashes: Will Pucovski's history of concussion problems could mean the young opener is sidelined for at least part of the Ashes series, which starts on December 8 in Brisbane.

Australia Test captain Tim Paine was "devastated" to hear of Will Pucovski's latest concussion but has nominated Marcus Harris to step in should the opener prove unfit for the Ashes.

Pucovski was struck on the helmet by a ball in a net session while training for Victoria last week.
