Despite the setback, Australia managed to secure a 43-run victory in the match, taking a commanding 2-0 lead in the series. With Lyon sidelined, the spotlight now turns to the talented Todd Murphy, who is set to make his Test debut as Lyon's replacement for the upcoming Headingley Test.

Lyon's Century Milestone and Untimely Injury:

The second Test at Lord's marked a significant milestone for Nathan Lyon, as he became only the sixth player to feature in 100 consecutive Test matches for Australia. The five others are - Alastair Cook, Allan Border, Mark Waugh, Sunil Gavaskar and Brendon McCullum. His consistency and physical conditioning were on full display as he reached this remarkable achievement. 

However, his celebration was short-lived, as Lyon sustained a calf injury while fielding on the second day. Despite not bowling in the remainder of the match, Lyon displayed his fighting spirit by bravely batting with a hobble, contributing 15 runs in a crucial partnership with Mitchell Starc.

Todd Murphy Steps Up:

With Lyon ruled out, the spotlight now shifts to 22-year-old offspinner Todd Murphy. Murphy impressed during his breakthrough tour of India earlier this year, where he claimed 14 wickets in four Tests at an average of 25.21. 

His memorable debut performance in Nagpur, which included a seven-wicket haul, showcased his potential and marked him as a player to watch in Australian cricket. The young spinner now has a golden opportunity to prove his worth on the Ashes stage.

In preparation for the Headingley Test, Australia has made some changes to their squad. Matt Renshaw, the backup batter, has been released from the squad, indicating the team's confidence in their current batting lineup, particularly opener David Warner, who displayed his form with a crucial innings of 66 in the Lord's Test. 

However, Renshaw will remain in the UK as a standby option. On the bowling front, Michael Neser retains his place in the 16-man squad, adding depth to the pace attack alongside Pat Cummins, Mitchell Starc, and Josh Hazlewood.
