Australia will play Marcus Harris if young opening batsman Will Pucovski is unable to prove his fitness after missing training ahead of the Fourth Test against India starting on Friday.
Pucovski is in doubt due to a partial shoulder shoulder dislocation suffered in the field on day five of the drawn Third Test in Sydney.
With limited time to recover, given the short gap between Test matches, Harris is on standby to replace Pucovski who made 62 and 10 on his debut at the SCG.
“We’ll probably know tonight I reckon, whether he (Pucovski) will be right to go,” Langer said on Wednesday.
“It’ll either be a quick turnaround and he’s back up and into it, or it might be a few weeks.
“He’s a young guy, he has just played his first Test so mentally he’s going to be exhausted anyway.
“We’ll keep an eye on how he pulls up today.”
Harris, who has played nine Tests for Australia, has been part of the squad for the past month but not played any competitive cricket since early December with two Australia A games against the Indians where he made scores of 5, 26, 25no and 35.
The 28-year-old Victorian’s form isn’t overwhelming but he did make a double century in the Sheffield Shield against South Australia earlier this season.
“We’re really hopeful he will get up,” Langer said about Pucovski. “If he doesn’t then the obvious thing is Marcus Harris would come in.”
The Aussies are unlikely to make any other changes, although they’ll monitor the load of their pace attack, in particular Mitchell Starc who struggled at times in Sydney.
