Campbell, drafted from Norwood in the 2006 national draft, had nearly completed his first football session for several weeks before going down with the ankle sprain. The Crows are confident there is no further damage.
It has been a tough summer for Campbell, who had shoulder surgery at the end of last season and was restricted to running before Christmas. His times were excellent but he then hurt his back early in the year.
Adelaide is on Thursday expected to name a squad of 28 players for Friday night’s 7.40pm trial game against Norwood. Some other Crows-listed players will line up with the SA Under 18 side against Norwood reserves.
Below is a rundown of the status of various players who have been injured or on modified programs through the pre-season.
Rhett Biglands: His rehabilitation from a knee reconstruction is going well and he started running last Monday.
Brett Burton: Had knee surgery at the end of last season and spent much of the pre-season on a modified program. Rejoined the main training group earlier this month but is probably another couple of weeks away from playing.
Michael Doughty: Had a modified program for most of the pre-season because of some knee soreness but rejoined full training late last month and is ready to play.
Nick Gill: Injured a hamstring tendon at the start of the pre-season and had a couple of setbacks and then strained a calf.
Trent Hentschel: Will have his knee reconstruction this Saturday.
Luke Jericho: Had major shoulder surgery last August. Has been able to run for most of the summer, joined most football drills in recent weeks and should be cleared for competitive work early next month.
Ivan Maric: Had minor shoulder surgery last year and then a hip problem but resumed training earlier this month and should be ready to play in the NAB Cup.
Kris Massie: Fractured his cheekbone on January 8. He has resumed training, wearing a helmet, and should be cleared for full competitive training late next week.
Mark Ricciuto: Had a heavy cold late last month and now has a sore back.
Kurt Tippett: Hurt his neck before Christmas. Is back training with the main group and should soon be cleared to resume competitive work.
Bernie Vince: Had post-season knee surgery and was on a modified program for most of the pre-season. Is now back in full training but will not play this weekend.
