According to Japanese Autosport web, Yuhi Sekiguchi's participation is still not confirmed.
If you put "TBC (To be confirmed)" in the entry list at the moment, ACO will impose a large fine.
So the team couldn't put "TBC" in entry list.
However, Sekiguchi prioritizes SGT/SF and therefore may not be able to participate in LM24 due to quarantine.
In that case, the team would hire another international driver.
