Great Western will look to bounce back from yet another disappointing loss when they take on Moyston-Willaura in the Mininera and District Football League.
Great Western were leading by four goals at half time only to be run over the top of by Penshurst.
Penshurst, who are yet to have a real impact on the competition, showed signs of improvement against Great Western.
This was the Lions third loss from four games leaving them with a three and one record.
The Lions did however suffer some injuries, making rotations hard through the latter stages.
Bobby Garley and Joel Freeland head the list of senior players that are still under injury clouds with Freeland not having played since round one with a hamstring strain.
Great Western will welcome back Sam Cocks and Leroy O'Brien to the team which will certainly help.
"They will give us a little bit more pace and run in the middle," club president Rod Matheson said.
The match against Moyston-Willaura will be a difficult one for Great Western as the Pumas have only dropped the one game for the season.
"It will be a pretty tough assignment for the boys," Matheson said.
Moyston-Willaura lost to ladder leaders Tatyoon last week and will be looking to get back on the winner's list tomorrow afternoon.
Aiden Bell has been a dominant player this year up forward for Moyston-Willaura and will be one player Great Western needs to watch.
Cody Virgona will more than likely go into the contest hard to win his own football and Ben Hustler will be a target up forward.
Leigh Preston, who returned to the club at the beginning of the year, will be hoping to put in a third consecutive good performance.
If Great Western stick to their structures and dispose of the ball at a high efficiency rate, there is no doubt they will be competitive.
Having not won on their home ground this season, that will also provide the Lions with a much needed spark.
"We just need to put four quarters of football together," Matheson said.
"The forward line worked well for the first half last week and then fell away.
"You can't win a game by playing one good half."
Great Western will take on Moyston-Willaura from 2.20pm at the Great Western Football Oval tomorrow afternoon.
