Australian spinner Ashton Agar has left the team's tour of England due to illness.
The 19-year-old caught the eye with a knock of 98 on his debut in the first Ashes Test at Trent Bridge.
"Ashton has had a mild viral illness for the past week and needs some time to rest and recuperate," team doctor Peter Brukner is quoted as saying by Sky Sports News.
"It has been a long tour and while he has handled the pressure extremely well, we thought it would be a good idea for him to get home as soon possible to have a short break before preparing for the domestic season."
Australia will be bidding to avoid a 4-0 series defeat for the first time on English soil when the final Test gets underway at The Oval on Wednesday.
