Veteran Australian off-spinner Nathan Lyon produced one of the most sporting moments in Ashes history as he walked out to bat virtually on one leg during Day 4 of the ongoing Test at Lord's on Saturday, July 1.Australia lost their ninth wicket for 264 and it seemed like that would be the end of their innings as Lyon had injured his right calf muscle in the field during England's first innings. However, the off-spinner walked out to bat and was met with a thunderous round of applause and a standing ovation from the Lord's crowd.Nathan Lyon added 15 runs with Mitchell Starc for the final wicket, something which could be really crucial come the back end of England's chase. Fans on Twitter hailed Nathan Lyon for turning up with the bat despite having come to the ground in crutches.Here are some of the reactions:SKY HIGH 💙@Diggu33Nathan Lyon out there batting for his country despite being on crutches earlier in the dayCourage personified #Ashes #ENGvAUS #WTC25 #nathanlyon #Ashes23 #EnglandCricket #Australia #WTC #ICC2Nathan Lyon out there batting for his country despite being on crutches earlier in the dayCourage personified 🙌#Ashes #ENGvAUS #WTC25 #nathanlyon #Ashes23 #EnglandCricket #Australia #WTC #ICC https://t.co/EDi4HArn5zJames Buttler | Cricket Badger Podcast 🏏🦡🇺🇦@cricket_badgerFair play Nathan Lyon.

But Test cricket allowing concussion subs but not injury subs feels such an anomaly - be a surprise if that doesn’t change eventually.376Incredible effort from Nathan Lyon, barely able to walk and adds 15 for the final wicket - a standing ovation from the Lords crowd.

That last 30 minutes was very poor cricket, didn't think it was in the spirit of the game. England knew he couldn't run. Dreadful tactics by an "attacking" team I feel very bad for Lyon, what a champion to do that. Unreal bravery.#Ashes3England need 371 runs to win.

However, the hosts seemed to have done their homework as they employed the short-ball ploy that had worked so well for the Aussies.The plan began to pay off as Australia lost wickets at regular intervals. However, Lyon managed to the England players for that long in the field by walking out to bat despite being injured.Even the fans in the crowd began to seem restless as Starc and Lyon couldn't run much because of the latter's injury. This might just have lifted the spirits of the Australians, who will be keen to come out all guns blazing after the Tea Break.The target of 371 isn't beyond England's reach by any stretch of the imagination and that's why it promises to be an intriguing chase.
