On a night Melbourne celebrated their second win of the AFLW season, forward Ainslie Kemp couldn't believe her terrible misfortune at Whitten Oval when she hurt her knee in the final seconds of the match.

The worst fears the club had at the time were confirmed on Saturday when scans showed Kemp had damaged her anterior cruciate and medial ligaments in her left knee and will miss the rest of the season.

Kemp, 22, had already twice ruptured the ACL in her right knee, restricting her to just 10 matches in the first four years of the competition.

Demons AFLW football manager Daniel McPherson said the scans were devastating for all parties.
