Steve Smith Ruled Out Of Third Ashes Test

Steve Smith will not play in the third Ashes Test at Headingley.

Smith's fitness has been the talk of the Ashes series after he copped a bouncer to the back of the neck on day four of the second Test at Lord's.

The Australian batsman fell to the ground after being hit by a ball from paceman Jofra Archer and was taken from the field.

Smith returned to bat later in the day after passing concussion tests, but suffered dizziness and headaches when he woke up the next morning.

He was replaced on day five of the Test by Marnus Labuschagne under the newly brought-in concussion rule.

Smith sat out the Australian side's first training session in Leeds on Tuesday.

Smith had a long chat with coach Justin Langer while inspecting the pitch and talked with team doctor Richard Saw, cutting a dejected figure in both conversations.

Cricket Australia's concussion and head trauma policy dictated the only opinion that mattered in Smith's selection battle was that of Saw.
