Crows forward Ken McGregor's hamstring strain will stop him from playing against Port Adelaide on Sunday.

McGregor has started light running and expects to be ready to play in the last minor round.

There is also some doubt this week over defender Nathan Bassett, who missed the Western Bulldogs clash with a bruised hip.

The one addition to the injury list last weekend was Hayden Skipworth, who has a slight strain of the hamstring and should miss one or two weeks.

Bernie Vince will be cleared to play this weekend in the SANFL.
