Former St Kilda captain Nick Riewoldt believes Adelaide coach Don Pyke should consider dropping skipper Taylor Walker back to the SANFL after another sub-par game from the forward.

Walker was goalless and managed just 12 disposals, and didn't register a score during his side's loss to West Coast.

The 29-year-old has failed to fire in 2019, and Riewoldt believes he shouldn't be exempt from playing in the reserves, especially if his form warrants it.

โ€œI think just because youโ€™re captain doesnโ€™t mean youโ€™re immune to going back to the SANFL,โ€ Riewoldt told SEN Breakfast.

โ€œOne thing thatโ€™s really important in a football club is integrity of selection.

โ€œIf other players are falling into the category form-wise and effort-wise that donโ€™t meet the standards, well then everyone should be exposed to the same level of scrutiny and integrity in selecting the team.โ€
