Isaiah Washington — the embattled Grey's Anatomy star who used an antigay slur to address a coworker last fall — will not return to ABC's No. 1 drama when it returns for a fourth season next September, according to a source close to the situation.
The source adds that the studio’s decision was likely based on a pattern of suspicious behavior by Washington that, according to press reports, goes back as far as 1997 on the set of the TV show High Incident.

Last fall, Washington was accused of calling fellow actor T.R. Knight a ''faggot'' during an on-set bruhaha. He repeated the slur at the Golden Globes in January. Within days of the incident becoming public, Knight announced he was gay.

Meanwhile, Washington taped a public service announcement for GLAAD, saying that ''words have power,'' which aired during a repeat of Grey's in May.
