Washington, July 17 : Actor Kiefer Sutherland''s trial date for allegedly headbutting a fashion designer in May this year has been postponed indefinitely, according to a court spokesperson.

The 42-year-old star was allegedly caught in a row with Jack MCCollough, which left the stylist with a broken nose.

However, Sutherland maintained he confronted the designer after he barged past actress pal Brooke Shields, who backed up the TV star''s story, calling the incident "unfortunate".

The pair reportedly agreed on a settlement shortly after the incident, with the release of a joint statement in which Sutherland admitted he "regretted" the incident, reports Contactmusic.

The actor was still slated to appear in a Manhattan court on Friday (17Jul09) to face the charges, but a spokesperson for the district attorney''s office has confirmed the appearance has been put back until further notice. (ANI)
