AFL premiership ruckman Steven King will join a revamped St Kilda coaching panel next season.

The 31-year-old former Geelong captain will retire at the end of this season, having played 240 AFL games, the final 47 with the Saints including last year's grand final.

He played 193 matches with the Cats, captaining them from 2003-06 and was part of Geelong's 2007 premiership side, before being traded to the Saints less than two weeks later.

This year, King has been out of the Saints' side since round seven, spending most of the year in the VFL, with the club preferring young ruckman Ben McEvoy as Michael Gardiner's partner.

The Saints also announced former Essendon player Peter Berbakov would join their coaching staff, after serving as an assistant under retired Sydney coach Paul Roos.

"We are excited to have Steven and Peter join the club's coaching department and we look forward to their positive contribution to the coaching panel for the 2011 season," Saints coach Ross Lyon said.

Saints assistants Andy Lovell, Tony Elshaug and Stephen Silvagni will all depart the club at the end of the year.
