David Warner will leave England and link up with Australia A on their tour of Africa in order to gain some match practice.
The left-handed batsman was not included in the tourists’ side for the opening Investec Ashes Test, having been suspended until the Trent Bridge contest for disciplinary reasons.
Warner, who will remain a part of Australia's Ashes squad, will depart for Africa later this week and play matches against a Zimbabwe XI and South Africa A.
National selector John Inverarity said: “David has trained hard and been very supportive of the team and his team-mates during the past few weeks, but his preparation for the first Test was not ideal.
“He is in need of match practice and runs in the longer format and the Australia A games in Zimbabwe and South Africa will provide him with the best possible opportunity.
“David remains a member of the Ashes squad and will return to England at an appropriate time once we’re happy he has had adequate preparation in match conditions.
“Steve Smith will stay on with the Ashes squad for the full tour in England. As a consequence of this Aaron Finch will take over the captaincy of Australia A while Alex Doolan has been promoted to vice-captain.
“The NSP also announces that Ashton Agar has become an official member of the Ashes squad for the series.”
