Collingwood defender Matthew Scharenberg could be a trade target for rival clubs in the off-season, according to Fox Sports' Tom Morris.

Clubs reportedly believe that the South Australian "is attainable" in the trade period with the lure of a multi-year deal and guaranteed senior selection.

He is contracted for the 2020 season.

The 23-year old was dropped for Friday night's blockbuster qualifying final clash against Geelong and will instead line-up in a Pies-Cats VFL scratch match at the Holden Centre.

Selected with Pick No. 6 in the 2013 National Draft, injuries have hampered Scharenberg in the early parts of his career, undergoing three knee reconstructions.

He became a key staple of Collingwood's back six last year before rupturing his ACL in the club's round 19 clash against Richmond.

Scharenberg has played seven senior games this season, including the last five, but was one of the unlucky few to make way for the Pies' returning stars.
