Calder track management has barred jockey Rene Douglas from the grounds for an unspecified reason, notifying Douglas of the action during Friday's card.
"Calder Race Course has refused Rene Douglas access to the racetrack for an indefinite period of time as of the close of business on Friday based on our rights as a private property owner," said Calder's president, Ken Dunn. "We have no further comment on the matter at the moment."
Douglas also refused to comment on the situation when reached in the paddock just before Friday's last race.
