St Kilda ruckman Paddy Ryder has been ruled out for the remainder of the season with a hamstring tendon injury.

The key big man came from the field in the dying stages of the Saints’ elimination final victory over the Western Bulldogs, with scans today revealing the extent of the injury.

Chief Operating Officer Simon Lethlean said it was really disappointing to lose a player of Ryder’s influence.

“It’s really disappointing for Paddy who has given everything to the club this season and played such an important role last night against the Dogs,” he said.

“Whether or not the injury requires surgery will be determined in the coming days after speaking with relevant experts.”

Lethlean said they would need the entire group to step up in Ryder’s absence.

“All teams face injuries to key players and we now have to find a way without Paddy,” he said.

“Part of the motivation for our group now is to make sure we don’t let him down and instead step up.”
