She's just giving herself the best chance to be 100 per cent for Saturday's A grade preliminary final contest between South Rovers and Merrivale.

Lions wing attack Mandy Knee was forced off the court in last Sunday's do-or-die battle with Panmure due to an ongoing ankle injury.

After visits to the beach twice a day this week as well as regular icing, she has declared herself a certain starter in Saturday's stoush with the Tigers.

"It's just a usual injury that's flared up," she said.

"I hurt it the week before against East (in the qualifying final) and it was a little sore before we started on Sunday but it just got progressively worse."

Knee took a seat on the bench after the fourth quarter against the Bulldogs, when scores were 38 apiece.

"We thought it would be better to make the change before overtime started rather than keep going on one leg," she said.

After 14 minutes of extra time, Rovers ended Panmure's season with a 46-43 victory.

Knee backed her side to upset minor premier Merrivale at Reid Oval on Saturday.

"I think we've just got a real even team across the board and even our bench is really strong," she said.

"We're a gritty, tough team."

"We played really well last time against Merrivale and I think we match up well on them."

"They've got a lot of experienced players who have played a lot of finals but I think we've got a good chance."

Knee also boasts finals experience, including an A grade premiership with Western Border club Hamilton Imperials.

While her career also included a State League stint in Melbourne, she crossed from Port Fairy in the off season.

"(South Rovers coach) Kylie (Carter) spoke to me earlier

in the year and I was looking to make the switch across," she said.

"All the girls have been very welcoming."

The recruit has had a stellar season, earning selection in the WDFNL team of the year.

She plans to continue her daily trips to the beach ahead of the preliminary final.

"It's freezing cold and it's not that much fun but (my ankle's) getting better so I'll keep doing it," she said.
