Melbourne and Parramatta will be sweating on the fitness of some of their stars after their thrilling clash last night.

Eels coach Brad Arthur conceded Maika Sivo's season is all-but-over after the winger suffered a knee injury.

Fellow winger Blake Ferguson is also in doubt for the second week of the finals after leaving the ground in pain late in the game.

โ€œI think Maika is done for the year,โ€ Arthur said after the game.ย 

โ€œThey think [Itโ€™s an MCL]. Look, itโ€™s a massive blow for the team but we have other blokes that need to step up.

โ€œItโ€™s sad for Maika, heโ€™s work hard and it was his birthday today but it what it is, itโ€™s footy.

โ€œFerg will have to have scans tomorrow, he might be a chance.โ€

Melbourne also came out of the game with a fresh injury concern to Cameron Munster.

The five-eighth came off the field with less than 10-minutes in the game with a suspected knee injury.

Munster previously missed matches this year due to an MCL sprain.
