Crows defender Nathan Bock will miss Saturday’s game against Fremantle at Etihad Stadium.

The club hopes Bock’s strained adductor - picked up during the third term of Saturday night’s game against St Kilda - will keep him out for only one game.

Two players came off the injury list on the weekend. Graham Johncock returned from his shoulder injury with Port Magpies in the SANFL on Sunday and Jarrhan Jacky was back with the Eagles after his long-term hamstring problem. Brad Symes also played his second game of the season with Central District.

Midfielder Bernie Vince (ankle) expects to start running this week but will miss at least one more game.

As reported late last week, Chris Knights (foot) and Will Young (knee) had surgery and will be out for about six weeks.

But Brodie Martin continues to make good progress from his knee injury and is now doing nearly all of the competitive drills at training.

Injury list:

Nathan Bock (adductor): 1 week
Bernie Vince (ankle): 1 week
Chris Knights (foot, plantar fasciitis): Indefinite
Brett Burton (knee): approx 4-5 weeks
Trent Hentschel (knee): 3 weeks
James Craig (hamstring): 2-3 weeks
Will Young (knee): 6 weeks
Brad Moran (knee): indefinite
Brodie Martin (knee): indefinite
Andy Otten (knee): season
