Marty Clarke has been dropped again by Collingwood.

Marty Clarke is back in the reserves.

The Down-man has been in and out of the Magpies side this year and has found it difficult to build momentum with his form.

He was first dropped in late June but produced a fantastic performance in the reserves to put himself back in the frame.

“Marty’s attitude has been expected but at the same time has been excellent,” coach Nathan Buckley said at the time.

He played the first ten AFL games for the Pies before being dropped for Round 12. He was recalled for Round 13, then dropped for Round 14, recalled for the next two matches before being dropped again.

After missing out in Round 17 he was back in the seniors last week for the facile win against the GWS Giants. He accumulated 16 disposals but coach Buckley has once again singled him out this week’s clash with St Kilda.

His compatriot team-mate Caolan Mooney is also out with an apparent hamstring injury.

Last weekend, Mooney score his first AFL goal before being subbed out.

Elsewhere, Tommy Walsh remains on the sidelines at the Sydney Swans while Niall McKeever has been dropped by the Brisbane Lions.

Zach Tuohy has retained his place for Carlton as they face the table-topping Sydney Swans, looking for their ninth straight win. The Blues are without the suspended captain and superstar Chris Judd.
