One South Fremantle premiership star will notch a significant mile- stone while another bows out of the WAFL in tomorrow's game against Peel at Fremantle Oval.
It is also an important match for the Thunder, with caretaker coach Mark Moody guiding the Mandurah-based team for the first time since Trevor Williams was sacked on Monday.
Spring-heeled forward Paul Mugambwa will play his 100th game for the Bulldogs, while utility player Ryan Murphy is set to retire.
Mugambwa, who is the WA Football Commission's multicultural co-ordinator, is best known for some towering marks since making his league debut in 2005. The 31-year-old excitement machine kicked two goals in the South Fremantle side which beat Subiaco by 18 points in the 2009 grand final.
Former Docker Murphy, who has been used in a variety of roles in recent times, was a member of the Bulldogs team which romped to a 56-point victory over Claremont to claim the 2005 premiership.
Murphy, who has played 116 games, said increasing work commitments had forced his hand.
The 27-year-old won the John Gerovich Medal as South Fremantle's leading goal kicker in 2007 and kicked 50 goals in 48 games for the Dockers from 2004 to 2010.
Peel mentor Moody comes from a strong SANFL and amateur background, the 49-year-old South Australian serving as a player, administrator and coach.
He arrived in WA late last year to work as an assistant and match committee member under Will- iams before being thrust into the senior role at the club.
In other matches, Brad Cooper will make his debut for East Fremantle against West Perth in the Wheatbelt town of Kalannie today.
The Sharks, who lost to Subiaco by six points last Saturday, also added Jayden Schofield, Aiden Tropiano and Lewis Fasolo.
The Falcons, in a game they need to win to stay in touch with the top four, recalled forward Anton Saylor, ruckman Josh Donaldson and defender Joe Morrow.
Claremont, big victors in a Foxtel Cup quarterfinal against NEAFL side Mt Gravatt last week, meet Subiaco at Medibank Stadium.
