East Fremantle's round three clash with Subiaco at East Fremantle Oval on Saturday has been brought forward to 1.30pm from the traditional 2.15pm start time.
The colts game between the two clubs will now be played after the league clash, starting at 4pm, with the reserves bounce down set for 11am.
The Sharks opened their 2011 account with a win over Perth last week, but the port club has not enjoyed a good recent history against Subiaco.
East Fremantle's win over the Lions in round 21 last year ended a 20-game drought dating back to 2002.
Subiaco will be looking for their first win of the season after letting a lead slip in their season-opener against West Perth at Medibank Stadium last week.
