The Frisco Independent School District has placed a coach on administrative leave while an investigation is underway.
Administrators are looking into a complaint that Centennial High School Coach and teacher Todd Campbell made derogatory and racially insensitive remarks to students.
"The school district is conducting a thorough investigation," Superintendent Jeremy Lyon said in a written statement. "If these allegations prove true, FISD will take immediate and appropriate action, up to and including termination."
Lyon made it clear that comments by faculty members that are harmful to students "will not be tolerated."
The superintendent said no further information would be forthcoming pending the outcome of the district's investigation.
