<a href="https://www.cricketcountry.com/teams/Australia/">Australia</a> captain <a href="https://www.cricketcountry.com/players/Aaron-Finch/news/">Aaron Finch</a> insisted there will be no let-up in the intensity of the champions' training sessions at the World Cup after 'friendly fire' ended batsman <a href="https://www.cricketcountry.com/players/Shaun-Marsh/news/">Shaun Marsh</a>'s involvement in the tournament. <p></p> <p></p>Marsh suffered a broken arm batting against Australia fast bowler <a href="https://www.cricketcountry.com/players/Pat-Cummins/news/">Pat Cummins</a> in the nets at Old Trafford on Thursday ahead of their concluding group match against South Africa on Saturday. <p></p> <p></p>The consolation for Australia, already through to the semi-finals, is Marsh -- who has now been replaced in the squad by <a href="https://www.cricketcountry.com/players/Peter-Handscomb/news/">Peter Handscomb</a> -- had already fallen out of their first-choice side. <strong>ALSO READ: <a title="Australia have learnt and become stronger after the ball-tampering incident: Faf du Plessis" href="https://www.cricketcountry.com/news/cricket-world-cup-2019-australia-have-learnt-and-become-stronger-after-the-ball-tampering-incident-faf-du-plessis-865946">Australia have learnt and become stronger after the ball-tampering incident: Faf du Plessis</a></strong> <p></p> <p></p>"Shaun is still in surgery at the moment, currently," Finch told reporters at Old Trafford on Friday. <p></p> <p></p>"So we just wish him a speedy recovery. I think it hit the boys pretty hard yesterday. <strong>ALSO READ: <a title="Cricket World Cup 2019: Marsh, Maxwell injuries a warning sign for Indian batsmen against Starc, Cummins" href="https://www.cricketcountry.com/news/cricket-world-cup-2019-shaun-marsh-glenn-maxwell-injuries-a-warning-sign-for-indian-batsmen-against-mitchell-starc-pat-cummins-865823">Marsh, Maxwell injuries a warning sign for Indian batsmen against Starc, Cummins</a></strong> <p></p> <p></p>"It was just unfortunate that it hit him where it did. An inch lower, an inch higher, and he would be fine." <p></p> <p></p>Shortly before Marsh's injury, all-rounder Glenn Maxwell -- batting in the very same net -- was struck a painful blow by left-arm fast bowler Mitchell Starc, the tournament's leading wicket-taker. <strong>ALSO READ: <a title="Australia eye top spot against South Africa" href="https://www.cricketcountry.com/news/cricket-world-cup-2019-australia-eye-top-spot-against-south-africa-865807">Australia eye top spot against South Africa</a></strong> <p></p> <p></p>Asked if the Australia quicks were being fed "red meat", a smiling Finch replied: "No, it was just one of those freak things. Shaun got a bouncer that sort of followed him a little bit. <p></p> <p></p>"We always pride ourself on competitive net sessions. We think that keeps you very sharp as a batsman in particular and it was one of those unfortunate things. <p></p> <p></p>"Maxxy, the one that he got just didn't bounce quite as much as he expected, it hit him on the arm, so yeah, it was no fault of anyone really. <p></p> <p></p>"It was guys being competitive in the nets and guys making sure that each and every one's as prepared to play as and when required." <p></p> <p></p>Finch, however, was pleased the likes of Starc were not easing up heading into the knockout phase. <p></p> <p></p>"They were out for a really good bowl yesterday having a couple of days off," he said. <p></p> <p></p>"There's obviously no malice or anything in it. It was never ideal, but at the end of the day, these things happen in the game." <p></p> <p></p>Saturday's match will be the first time Australia batsmen Steve Smith and David Warner have faced South Africa since they were given 12-month bans for their roles in a ball-tampering scandal during a Test match in Cape Town. <p></p> <p></p><strong>- 'Outstanding sportsmanship' -</strong> <p></p> <p></p>But Finch said the fact Australia were playing the Proteas would not provide the pair with any extra incentive. <p></p> <p></p>"I think everyone's moved on," he insisted. "There's definitely never any more or less motivation than international cricket itself. <p></p> <p></p>"It's coming to the business end of the World Cup. There's not much more motivation needed from that." <p></p> <p></p>The ball-tampering affair was one of several unsavoury incidents during a fractious series with a South Africa side prepared to "sledge" back in response to Australia's verbal taunts. <p></p> <p></p>But Finch was confident he would not have to keep his players in check on Saturday. <p></p> <p></p>"No, there will be no restraint needed," he insisted. "The spirit in which the World Cup has been played has been unbelievable. <p></p> <p></p>"The sportsmanship, the camaraderie amongst the teams has been outstanding. <p></p> <p></p>"I think Australians and South Africans are quite similar in a lot of ways. They are very competitive people, passionate about the game."
