St Kilda midfielder ruled out for the season

Koby Stevens won’t play again this season.

The St Kilda midfielder has been battling the effects of delayed concussion.

He last played in round two.

The tough onballer suffered the injury in the first game of the season.

It’s another blow for the struggling Saints, who have also lost Dylan Roberton for the year after he collapsed against Geelong.

He’s being monitored for a heart condition.
