Carlton list boss Nick Austin has confirmed that Lochie O'Brien will be at Carlton in 2021.

In recent days, rumours swirled linking the 21-year-old to a move to Collingwood ahead of the Trade Period deadline.

Austin spoke on AFL Trade Radio, saying the Blues have categorically ruled out the club trading the former top-10 draft pick.

“There’s a lot of speculation that goes along during this period and this is one of those,” he said.

“I can categorically say that Lochie O’Brien will be a Carlton player in 2021 and we’re really excited for him to have a big pre-season.

“I know Lochie would have wanted to play more senior footy this year, but hopefully he can have a big pre-season and work his way back into calculations.

“I think it’s a great thing for our footy club that we have depth in some key roles in the square and inside.

“Lochie will be a Carlton player in 2021.”

O’Brien managed just one game this season and is contracted until the end of 2021.
