Four clubs have added players to their long-term injury lists (LTI), after AFL spokesman Patrick Keane confirmed the list changes on Thursday night.

Geelong have moved key defender Lachie Henderson to the LTI, and have re-instated Quinton Narkle to the senior list as he nears a return from an ACL injury suffered last season.

The Cats have upgraded Mark O'Connor in place of Henderson.

The Bombers have moved defender Martin Gleeson to the LTI, while Hawthorn have placed veteran defender Grant Birchall on their LTI.

Finally, the Eagles have moved forward Daniel Venables to the club's LTI.

As per AFL rules, players cannot play AFL or VFL football for six weeks after being placed on the long-term injury list.
