Not a lot of information but we have this
Nick Blakey
Midfielder/forward
194cm/75kg
Swans academy/NSW-ACT
27/2/2000
Three clubs will fight for Blakey's services next year, with the midfielder able to join North Melbourne and the Brisbane Lions as a father-son prospect (his father John played with the Roos and Fitzroy) and also the Swans as an academy pick. Sydney appears the early favourite, but Blakey will be hoping for more luck with injury next year after a back concern ended his 2017 campaign early. At his height, Blakey is considered a utility who can be used anywhere.
