( CNN ) NASCAR announced Wednesday that it has lifted its suspension of driver Kurt Busch , making him eligible to return to the sport immediately -- albeit `` under indefinite probation . '' Busch was suspended after a Delaware civil court found that he probably committed domestic violence against his former girlfriend , Patricia Driscoll . She accused the standout driver of grabbing her by the throat and slamming her head against a wall in his motor home at Delaware 's Dover International Speedway in September . Twice , the NASCAR 2004 Cup champion appealed his indefinite suspension and lost both times . That meant he missed the season-opening Daytona 500 as well as two subsequent Sprint Cup races . But he should be able to compete through the fall , and NASCAR says that it will waive its requirement for him to compete in all championship events . The case against Busch took a significant turn last week , when the Delaware Department of Justice announced that charges would not be filed against him . `` As I have said from the beginning , I did not commit domestic abuse , '' Busch said then . `` I look forward to being back in racing as soon as possible and moving on with my life . '' A Kent County , Delaware , family court commissioner ruled in February that Busch must stay away from Driscoll for a year . NASCAR officials decided to lift Busch 's suspension because he complied with the requirements of the racing circuit 's reinstatement program , completed behavioral assessments and got the OK from a behavioral health care expert to race again . He 's not totally out of the woods . In a news release , NASCAR said Busch must `` undergo additional steps to address the behavior for which he was penalized . '' Steve O'Donnell , NASCAR executive vice president and chief racing development officer , said the lack of charges against Busch expedited his return . `` We have made it very clear to Kurt Busch our expectations for him moving forward , which includes participation in a treatment program and full compliance with all judicial requirements as a result of his off-track behavior , '' O'Donnell said . CNN 's Jill Martin contributed to this report .
The lack of charges against Busch expedited the lawsuit , a NASCAR official decision . Kurt ##sey was accused of grabbing his ex - girlfriend by the police , shaking her head . He twice appealed NASCAR 's indefinite suspension and lost .
