Defending champions Great Britain will go into tomorrows final showjumping phase as the overnight leaders following an exciting cross-country day at the Paris Olympic Games that triggered a shake up of the leaderboard.Laura Collett, Tom McEwen and Ros Canter all jumped clear around the 28-fence course, which was designed by Pierre le Goupil. However, Laura picked up 0.8 of a penalty for finishing two seconds outside the optimum time and Ros was handed 15 faults for missing a flag.Ros Canter and Lordships Graffalo help Team GB hold on to goldRos and Lordship Graffalos penalties are currently under review by the ground jury. They are in provisional 24th place overnight.If the penalties stand, it means Team GB will only have a single fence in hand tomorrow over the host nation, France.Tom McEwens penalty-free round aboard JL Dublin the horse formerly campaigned by Nicola Wilson and ridden to dual European gold by her in 2021 puts them in sixth place on the individual standings.Tom is looking to defend or better the individual silver he won in Tokyo.Mixed day for GermanyIndividually, Laura and London 52 have slipped from pole position after dressage to sit behind Germanys Michael Jung on Chipmunk FRH.The latter pulled off a textbook clear and added nothing to his first-phase score, putting him firmly in the hunt for individual Olympic glory tomorrow.Will Michael Jung win his third individual Olympic gold in Paris? Photo FEI/Liz GreggIf Michael wins gold, it will be his third Olympic title. His last victory came at the Rio 2016 Games, where he became the third event rider to achieve back-to-back individual golds following his success at London 2012.However, Germany is out of the running for a team medal, due to second rider Christoph Wahler and Carjatan S parting company after the drop at fence 16.A fall of horse or rider means instant elimination and although Germanys reserve rider can be subbed in to showjump tomorrow, doing so incurs 200 penalties.Britains leadBritains team score is now 82.5, while France is on 87.2. Every showjump knocked down tomorrow costs four penalties, while one time-fault is added for every second over the optimum time.France, the team champions in Rio, occupied third after dressage.Laura Collett and London 52 hold silver overnightJumping clears today from teammates Karim Florent Laghouag (riding Triton Fontaine), Stephane Landois (Chaman Dumontceau, who picked up 2.8 time faults) and Nicolas Touzaint (Diabolo Menthe, who collected 3.2 faults for time) puts them in silver overnight.Japan eyes historic medalTeam Japan is now sitting in bronze on a score of 93.8. If they win a medal tomorrow, it will be a first for this country in the history of Olympic eventing.Yoshi Oiwa piloted the former Pippa Funnell ride MGH Grafton Street her Burghley CCI5* winner in 2019 home clear and inside the time to lie fifth individually.Kazuma Tomoto occupies eighth with Vinci De La Vigne.Their teammate Ryuzo Kitajima is currently outside the top 20 aboard Cekatinka.Trouble for New Zealand and USAJapan has an 8.6-penalty advantage over Switzerland tomorrow. Belgium lies fifth on 111, ahead of New Zealand with a score of 118.2.The latter nation was in the hunt in fourth place after dressage but pathfinder Jonelle Price (Hiarado) had a run-out at the angled birch rails at fence 7b and incurred28.4 penalties in total.Clarke Johnstone picked up 4.8 time-faults with Menlo Park, while Tim Price and Falco added two for time.Sweden now lies seventh on 120.1, ahead of Ireland on 121.1.The USA is ninth overnight with 128.5 penalties after a run-out plus time-faults for Caroline Pamukcu and HSH Blake left them outside the top 45.Boyd Martins 1.6 time-faults aboard Fedarman B places him 17th individually, while Elisabeth Halliday and Nutcrackers six time-faults leaves them 22nd.The Netherlands rounds off the top 10 teams with a two-phase total of 147.5.Australias hopesAustralia eighth as a team after dressage dropped out of the reckoning when Kevin McNab quickly pulled up a lame Don Quidam. They retired, picking up 200 penalties in the process.There were, however, two stand out performances from Shane Rose and Chris Burton.First out was Shane, who brought Virgil home clear with 2.8 time-faults to add. He is not long back in the saddle after an awful fall earlier this year in which he suffered 18 fractures.Shane was in a wheelchair and had to learn to walk again before he could even think about getting back on a horse let alone being selected for Paris.Later in the day, team anchor Christopher Burton and Shadow Man confidently motored around the course to finish penalty free.They now lie third individually but have no margin for error, as Swiss rider Felix Vogg is just 0.1 of a penalty behind with Dao de LOcean.Margins for errorThe top eight riders on the individual leaderboard are within 10 penalties of each other. It means medals could be won and lost tomorrow with a single pole down.Michael Jung has no fence in hand over Laura Collett, who in turn has no fence in hand over Chris Burton or Felix Vogg.Yoshi Oiwa and Tom McEwen are a handful of penalties behind on 25.5 and 25.8 respectively.They are less than a fence ahead of Frances Stephane Landois (27.2) and Kazuma Tomoto (27.4).New Zealands best chances lie with Tim Price, ninth at the moment on Falco with a score of 28.5.He is a fraction ahead of another Frenchman Karim Florent Laghouag by just 1.1 penalties.Useful linksView the full team standings after showjumpingView the full individual standings after showjumpingTomorrows showjumping phase runs in reverse order of merit.
