COMEBACK Kangaroo Majak Daw's season is over, with a hamstring injury suffered in the VFL on Saturday ending his hopes of playing in the AFL in 2019.

Daw was playing his fourth state league match in a row since recovering from serious hip and pelvis injuries he sustained in a fall from Melbourne's Bolte Bridge in December.

He was running at high speed in the game against Carlton's VFL affiliate Northern Blues when he "stumbled forward" and tore his left hamstring, the club's football boss Cameron Joyce said.

"With only four games until the end of the season, unfortunately he won't be able to recover in time to make it back to playing this season," Joyce said.

"The scans revealed a decent tear and it would normally be a six-week injury."

The Roos were planning for Daw to play unrestricted minutes for the first time and had kept the door ajar for him to play in the AFL this season before the injury setback.

"Each week he played, we carefully increased his minutes by a quarter and he was set to play his first full game on Saturday," Joyce said.

"It's really disappointing for him not to be able to get back for an AFL game, which was his goal, but he should take a lot of confidence out of his incredible effort in getting back to playing so quickly, considering the injuries he had.

"No one should underestimate the level of determination, courage and willpower Majak has shown over the past six or so months.

"We will now ensure he has all the support he needs to come back stronger and ready for day one of the 2020 pre-season."

Daw has already re-signed for next year, when he will attempt to add to his 50 senior matches.
