Charlotte, N.C. ? Sticking with its “boys, have at it” attitude, NASCAR placed Carl Edwards on probation for three races Tuesday for deliberately wrecking Brad Keselowski’s car last weekend in Atlanta. Edwards will be monitored by NASCAR through the April 10 race at Phoenix but may drive in the Sprint Cup and Nationwide Series.

NASCAR president Mike Helton said Edwards acted unacceptably Sunday but did not cross the line in what the sanctioning body will allow this season. NASCAR promised in January to give the drivers more leeway in policing themselves and settling scores.
