Ben Stokes and Jos Buttler will resume the England innings from an overnight score of 96/4 as the hosts have managed to take a slender lead of 104 runs.
But Archer's antics on day four of the Test match will not be forgotten in a long time as he bowled a lethal spell to Australian batsman Steven Smith. Australia were cleared to use Marnus Labuschagne as a replacement for the 30-year-old on Sunday, with the first concussion substitute in Test history helping the tourists secure a draw with a gritty half-century.
He became one of the most feared fast bowlers in the world and his prowess for terrifying batsmen was evident during the 2013-14 season, when he took 59 wickets in eight Tests against England and South Africa.
Smith's participation in the third Test which gets underway from Headingley on Thursday is in doubt as he recovers from a concussion caused by the Archer hit.
"Potentially. He's come in and he really has made a massive impact, added a different dynamic to our bowling group and has given Australia something different to think about", said Root.
Archer's performance at Lord's on his Test debut will give England real hope, though.
"He makes things happen with such a unique action and natural pace, which is always in the game on any surface".
Anderson did not play in the second Test because of a calf injury that restricted him to just four overs in Australia's 251-run win in the series opener at Edgbaston.
With Australia now holding a 1-0 lead, the English need to win two of the final three Tests to take it off their fierce rivals.
"A draw for the second Test but it was a total Ashes foul for the crowd at Lord's to boo Steve Smith", the politician wrote, as well as posting a picture of Smith sitting inside the famous Lord's Long Room.
