The season is over for St Kilda's Sam Flanders, who suffered a ruptured Achilles in the Saints' loss to Hawthorn.
Flanders was helped from the field after being injured in the second quarter of the 52-point defeat at Marvel Stadium on Thursday night.
St Kilda on Friday confirmed the 24-year-old had ruptured his Achilles and will miss the rest of the season.
It was another sour note to a disappointing night for the Saints (5-7), who failed to kick a goal in the first half against the high-flying Hawks (8-1-3).
GWS forward Jake Riccardi will miss at least two months, part of a massive double injury blow for the Giants.
Riccardi underwent surgery for ankle syndesmosis after injuring himself in the dying stages of the Giants' 78-point win over the Brisbane Lions.
