CHARLOTTE, N.C. — The crew chief for Nationwide Series driver Brendan Gaughan was suspended indefinitely Thursday for using a racial slur about rival driver Marc Davis, who is black.

Bryan Berry apparently used the slur as he walked toward the Nashville Speedway garage to confront Davis during Saturday night's race. At least two people heard the slur and reported it to NASCAR, which investigated the claims before suspending Berry.

The 19-year-old Davis did not want to comment on the incident.
