Australia's wicketkeeper Matthew Wade is expected to take no further part in the third day's play against Pakistan in Sydney after returning to the team hotel due to illness.
Rain delayed the start of play until 2.35pm and Wade took the field with the team when play finally began, but he was able to keep wicket for only two overs before he left the SCG.
"Matthew felt ill this morning and has had nausea and diarrhoea," Australia's team doctor Peter Brukner said. "He's received medication for his symptoms but is still feeling unwell. After taking the field he realised he was not well enough to continue, hence his decision to come off. He's returning to the hotel to rest and will hopefully recover by tomorrow morning. We will monitor his condition."
Wade was replaced behind the stumps by Peter Handscomb, who has kept wickets in nearly 50 matches across first-class, List A and Twenty20 matches. Although he rarely keeps in Sheffield Shield matches these days, Handscomb performed the role in four Matador Cup games this summer and is expecting to do so in the BBL this month as well.
"The gloves stay in the bag and the pads only come out for a bit of bat-pad work," Handscomb said when asked about his wicketkeeping in the lead-up to this Test. "When I'm not keeping it's pretty much full-time batting and fielding, because I need to be able to catch like a fielder.
"Then as soon as I go back to Big Bash and put the gloves on I'll do some work there and make sure that my skills are up to date ... I think I'd be able to do it as a last call if no one else was around. I can chuck the gloves on, that would be fine."
