SYDNEY -- Australian track athlete John Steffensen has threatened to boycott the London Olympics after alleging racism because he was not selected to run the 400 meters.
Steffensen, in a TV interview, accused Athletics Australia of racial vilification and said he would bypass the games in protest.
The dual Commonwealth Games gold medalist was upset after an individual 400 berth was granted to teenager Steve Solomon, who also achieved an Olympic qualifying time.
Steffensen, who is of aboriginal descent, was selected only as a member of Australia's 4x400 relay team.
Athletics Australia chief executive Dallas O'Brien denied the claims in comments published on Sunday and said his group had a contingency plan if Steffensen followed through with his threat not to compete.
