Michigan International Speedway has confirmed that it will not host an IRL IndyCar Series round in 2008.
It will be the first time in the track's 40-year history that it has not had a open-wheel race on its schedule.
Track president Roger Curtis said he was disappointed that Michigan had not been able to reach agreement with the IRL.
"Since its inaugural running in 2002, Michigan International Speedway, the state of Michigan, city of Jackson and other local communities made a major commitment to growing the IndyCar Series event," Curtis said.
"I had hoped that we'd be able to reach an agreement with the IRL for 2008 given our historical investment in open-wheel racing that dates back four decades."
Prior to linking up with the IRL in 2002, Michigan had hosted Champ Car races, including the Indianapolis 500 rival event the US 500 in 1996.
Curtis added that the loss of the IndyCar date did not mean that Michigan would focus solely on NASCAR, as the circuit was investigating the possibility of adding a road course layout.
"Michigan International Speedway will continue to seek growth opportunities by exploring the feasibility of developing a road course for potential rental and appropriate spectator events as well as other ancillary events that utilise the track facilities," he said.
Michigan's final IndyCar race will take place on 5 August this year.
