Cox trained with the Power on Saturday but list manager Jason Cripps says he’s not what the club is looking for.
“We’ve decided not to offer Mason a contract for a couple of reasons,’’ Cripps told The Advertiser.
“And from a list management perspective we saw Mason as being a long-term project, having not played the game before and where he’s at with his development, rather than a short-term fix for our ruck stocks.
“Mason’s a long-term project and is not someone we can count on to come in next year and have an impact,’’ Cripps said.
“We look to improve every year through our list management process and from the weekend with Renouf going down and Reddo (Jarrad Redden) out for the rest of the year we will continue to address that (ruck) area, along with our entire list.’’
The 23-year-old former soccer player and basketballer has North Melbourne, Collingwood and Richmond still pursuing him and can officially join his preferred club at the end of the year.
Cox arrived in Australia last week after being the standout prospect at the AFL’s US Combine.
He spent time at Arden Street last week and attended the game against the Cats on Friday night.
Cox has impressed clubs with his speed, agility and clean hands.
