Super Formula veteran Koudai Tsukakoshi is to replace Tatiana Calderón at Drago Racing for this weekend’s Super Formula round at Okayama.
With only four days until drivers are required to sign-on at Okayama, Calderón will not have time to sufficiently quarantine in order to take part in the event, allowing Tsukakoshi to claim his 82nd start in the series.
In a successful run at Le Mans for her inaugural 24-Hour Race, Calderón secured 9th in the LMP2 class (13th overall) in the Gibson-powered Richard Mille Racing entry, alongside Sophia Flörsch and Beitske Visser.
Calderón made her Super Formula debut at Motegi last month and enjoyed a respectable race, finishing 12th after keeping double-champion Naoki Yamamoto at bay in the final laps. It is expected that Calderón will return for the 3rd round at Sportland SUGO in mid-October.
Tsukakoshi, meanwhile, is a race winner in Super Formula, having taken victory at Autopolis in 2012 on his way to finishing runner-up in the standings to Kazuki Nakajima; however, the 33-year-old has spent much of his time in the series collecting points semi-regularly in the lower end of the top ten.
Alongside teammate Bertrand Baguette, Tsukakoshi currently leads the Super GT Series, having taken two wins from the first four races.
