HARD-LUCK Kangaroo Ed Vickers-Willis' comeback from a major knee injury has suffered a setback, with the defender dislocating a toe at training on Tuesday. 

Vickers-Willis was completing full training after not playing since sustaining an anterior cruciate ligament rupture in his left knee against Fremantle in their season-opener last year.

There was teammate concern at the sight of Vickers-Willis again hobbling off the track after a marking contest, with Jared Polec and Jamie Macmillan among those to check on his status. 

Another injury-cursed Roo, Taylor Garner, also exited training after feeling some hamstring tightness, while key forward Nick Larkey is nursing a sore left foot and trained inside on Tuesday.

Vickers-Willis underwent an arthroscopy to repair some issues in his injured knee in November after feeling some discomfort, but was otherwise tracking well.

He had a preliminary assessment while still on the ground on Tuesday, where the toe problem was diagnosed, before leaving for a scan. 

Vickers-Willis has played only 15 games, and never more than seven in a season, since being the No.36 selection in the 2014 NAB AFL Draft.

He is out of contract at season's end but is a popular figure at Arden Street and has looked assured at AFL level whenever he's appeared.
