Smith decision to miss third Ashes Test a 'no brainer': Langer

Australia's star batsman Steve Smith has been ruled out of the third Ashes Test beginning on Thursday after suffering concussion, a decision which coach Justin Langer said was a "no brainer".

The 30-year-old Smith -- who has scored two centuries and 92 in his three innings in the first two Tests -- was felled by a Jofra Archer bouncer on Saturday in the first innings of the second Test at Lord's.

Smith's absence will be a huge blow to Australia who hold a 1-0 lead in the five Test series and for whom victory at Headingley would ensure they retained the Ashes.

Their other batsmen have not looked convincing -- experienced opener David Warner has totalled just 18 in his four innings -- with Smith being the lynch-pin.

"When we followed the protocols he was probably a couple of days off being fit to be selected," said Langer at a press conference.

"It was really a no-brainer. He felt a bit better yesterday but he's not going to have enough time to tick off everything he's got to do."
"We have to make sure our senior players and the younger guys step up and fill what are almost unfillable shoes because he's the best player in the world."
