Nippon Professional Baseball and the J. League may use on-site novel coronavirus testing as a way to help each league to remain on schedule as much as possible, the associations said Monday after a meeting of their joint COVID-19 task force.

A J. League contest between Gamba Osaka and Nagoya Grampus was postponed two hours before kickoff last week after four Gamba players and a staff member tested positive for the virus.

The task force is considering on-site testing since going through health centers to identify positive cases and close contacts takes time — an issue that could be resolved by installing the same testing system in stadiums.
