Fremantle forward Michael Walters has gone down with a hamstring injury against Carlton this afternoon.
The Dockers goal sneak limped off late in the last quarter and went straight down the race with medical staff.
He reemerged shortly after but spent the remainder of the game sitting in the back row of the bench with his left hamstring heavy iced.
Walters has been an very important player for the Dockers this year and with only two games to go his season may be finished.
The severity of the injury is yet to be confirmed by Fremantle officials.
