London: Marnus Labuschagne became the first concussion substitute in Test cricket replacing Steve Smith, as Australia drew to England in the second Ashes Test of the series.
Smith retired hurt on 80 on Saturday after being hit on the neck by a Jofra Archer bouncer, but passed concussion tests and returned to make 92.
A delayed-onset concussion for Smith meant Labuschagne was brought in for the final day of the Test at Lord's.
The 25-year-old was also victim to an Archer bouncer, which hit him on the grill of the helmet, but Labuschagne was quick to convince umpires that he didn't need to leave the field.
Labuschagne told the umpires "I know where I am, I know the Test, I know how many I'm on, I'm on zero and that was a fast bouncer," before going on to make 59 in Australia's second innings.
