The inaugural season of Grand Slam Track has reportedly come to an abrupt end.

The fourth and final stop of the league was scheduled for Los Angeles on June 28 at UCLA's Drake Stadium, but according to multiple media reports, that stop was to be cancelled on Thursday.

A person with knowledge of the Grand Slam Track decision told the Associated Press it was due to economic issues with the venue. The person added the new track league, founded by U.S. sprinting great Michael Johnson, is looking toward 2026 and is expected to announce new investors next week.

The person spoke on condition of anonymity because the decision hadn't been publicly announced. A meeting with the athletes was slated to take place later Thursday.

The inaugural season began in Kingston, Jamaica, in early April before meets in Miramar, Fla., and Philadelphia last month. Philadelphia's meet had its schedule condensed from three days, like the previous two Slams, to two days.

Canada's Marco Arop was the lone Canadian athlete to commit to the full season and competed in the three previous meets. The 26-year-old from Edmonton won the short distance Slam title in Philadelphia.

The first three events doled out about $9.45 million US in prize money, with another $3 million expected to be paid in L.A. Bonuses were expected to go to season-long winners of the categories.
