After injuring her right knee in the Bendigo Spirit's win over Dandenong on Saturday night, Penaluna spent Sunday hoping the injury was not as serious as first thought.

However, scans on Monday revealed Penaluna had ruptured her anterior cruciate ligament and torn her meniscus.

"It's hit me pretty hard today,'' Penaluna admitted.

"I was hoping inside it wasn't bad, but it didn't turn out that way.

"It is what it is, I guess. I'll be heading back to rehab.

"Another  12  months in rehab won't be much fun, but it's got to be done."

Penaluna spent the best of two years on the sidelines after having a knee reconstruction on her right knee in late 2011.

She was starting to return to her best form with the Spirit before Saturday night's incident.

"I caught the ball, went to turn, my foot didn't move but the rest of my body did,'' Penaluna said.

"No-one touched me, it was just one of those things.

"Straight away I knew it was serious... I was just hoping it wasn't a reco."

LARS surgery is an option for Penaluna, but she won't make a final decision until the end of this week.

"I see my surgeon on Thursday and I'll see what he recommends,'' she said.

"I haven't really thought about LARS surgery. I'll see what the surgeon says.

"I'll do whatever the medicos tell me."

Penaluna plans to be courtside with the Spirit as the club chases a second-straight WNBL championship.

"I'm going to stay positive for the girls and I want to be part of the group as much as I can,'' she said.

"Through the winter I'll watch the Lady Braves as well and stay involved in basketball."
