West Coast AFL coach John Worsfold has been forced to issue an apology to Perth's media representatives, after using the term "spastics" during an angry exchange at Subiaco Oval on Wednesday.

The incident occurred as West Coast trained ahead of Thursday night's opening game of the season against St Kilda.

Worsfold ran 50m to confront media representatives from various outlets, admonishing them as they gathered to conduct a pre-arranged interview with Fremantle Dockers assistant coach Michael Broadbridge.

After reaching the sideline, Worsfold's asked reporters: "Are you f...ing spastics", before angrily asking for cameras and reporters to move off the grass while training was in progress.

In a statement released by the club, Worsfold said he wished to apologise to anyone whom he offended by using the term.

"I am deeply sorry for any hurt or anguish I have caused anyone through my statement," Worsfold said.

"It was an extremely poor choice of words and something I truly regret.

"It was a spur of the moment reaction, but that in no way justifies the terminology I used."

The club had previously asked journalists to remain outside the Subiaco Oval fence during training, after reporters at a training session earlier this year overheard and reported Worsfold admonishing his players for their ill-discipline.
