He had a quad injury as well, couldn't be far away http://au.news.yahoo.com/thewest/sport/a/-/sport/13453473/afl-injury-list-after-round-3/
http://injuryupdate.com.au/afl-injury-list.php This site appears to be up to date with injuries, Danny Stanley's listed as - quad strain - test. Should be back this week or next.
Played half a game in the NEAFL last week after 2 weeks off with a quad, so with the GC injury concerns he might be back this week as the sub or maybe play a full game in the NEAFL.
