Robert Buckley will join the cast of The CW's One Tree Hill for its seventh season, says The Hollywood Reporter.

The former Lipstick Jungle star will play Clayton, a young sports agent who represents James Lafferty's basketball player Nathan and becomes his close ally.

Brian Austin Green had previously been in talks for the role but could not make a deal with the show's producers.

The forthcoming season of One Tree Hill will be the first without Chad Michael Murray and Hilarie Burton. The storyline will reportedly advance a year from the end of season six.
