Collingwood wingman Tom Phillips could be a "trade target" for rival clubs at the end of the season, according to The Herald Sun.

Phillips is spending more time forward this year and has struggled to back up his impressive form from the last two seasons.

The 24-year old averaged 25.6 disposals and 5.5 marks over the 2018 and 2019 campaigns combined.

He is going at 15.1 disposals and 2.5 marks this season, albeit in shortened quarters.

Geelong were keen on acquiring Phillips last year, but the midfielder was not willing to entertain a trade.

With the Pies managing a tight salary cap and looking to re-sign Jordan De Goey, Darcy Moore and Brody Mihocek, Phillips' name could well come up in trade discussions again.

The Herald Sun reports that out-of-favour big man Mason Cox could also search for senior opportunities elsewhere at the end of the season.
