Tim Knox and Bud Moore have been placed on indefinite administrative paid leave.
NASCAR will not reveal the identities of the officials sent home Friday from Kentucky Speedway, but a person familiar with the investigation confirmed to the AP on Saturday that Knox and Moore were suspended.
The person requested anonymity because NASCAR's investigation is ongoing.
NASCAR did not give a reason for the men's suspension, and chairman Brian France cautioned against assuming the officials are being punished for allegations made in the lawsuit.
"Obviously we found some violations in our policy, but I would not jump to conclusions to assume that all of the allegations that were made are accurate," France said at Michigan International Speedway, the site of today's Sprint Cup Series race.
Mauricia Grant filed her suit Tuesday, alleging 23 specific incidents of sexual harassment and 34 specific incidents of racial and gender discrimination during her time as a technical inspector for NASCAR's second-tier Nationwide Series.
Grant, who is black, claims her October 2007 firing was retaliation for complaining about the way she was treated on the job from her January 2005 hiring.
