The Michael Johnson-led Grand Slam Track has been warned by World Athletics that it may not be permitted to return in 2026 even if it pays off its huge debts.
Court documents released on Monday showed that the league, which filed for Chapter 11 bankruptcy last week, still owes some of the biggest names in track and field hundreds of thousands of dollars and creditors between $10m and $50m (£7.5m and £37.3m).
