SAM WEIDEMAN and Kade Kolodjashnij's frustrating seasons have come to an end, with the Melbourne duo ruled out for the remainder of the year with injury.

Weideman has played 11 AFL games in 2019 after starring as a young key forward in last year's finals series. He has battled both form issues and a hip complaint this season before the latest setback of a broken jaw.

The 22-year-old was making his comeback from a calf injury in the VFL last weekend when he collided with teammate Declan Keilty in the opening minute of the match.

He was left with concussion and had surgery on Monday to repair two breaks in his jaw.

Recruit Kolodjashnij has had a wretched run with concussion, head knocks and whiplash in his 80-game, six-year career, managing to play just rounds two and three in the AFL this year.

His last match of 2019, a VFL game, came in mid-June before another head knock sidelined him.

"Obviously he's had multiple concussions, so we're being cautious with him," Melbourne elite performance manager David Misson told the club website.

"He's just come back from the Gold Coast after having a bit of time away with his family to just reset, but he's come back pretty enthusiastic to get going again.

"He won't play this year, but we're hoping we'll set him up for a good pre-season."

Meanwhile, star key back Steven May is "touch and go" to face Richmond's twin towers of Tom Lynch and Jack Riewoldt this weekend.

May missed last week's loss to St Kilda with a minor hamstring injury and will need to get through training this week in order to be passed fit to play.

With finals out of reach, Melbourne now has seven players out for the season: Jeff Garlett (shoulder), Kolodjashnij, Tom McDonald (meniscus), Aaron Nietschke (ACL), Joel Smith (groin), Weideman and Guy Walker (shoulder).
