Eight new Blues have found out their numbers, with Eddie Betts returning to his trusty No. 19.

2019 NAB AFL Draft pick No. 17 Brodie Kemp has been handed the No. 17 jumper after it was left vacant this year with the departure of Sam Rowe.

After arriving at the club on Friday, Jack Martin has been given No. 21 for his first season.

Marc Pittonet has moved clubs but he will still wear No. 27, his Hawthorn number for the last three seasons.

Jack Newnes will take the No. 32 guernsey, after being picked up from St Kilda as a delisted free agent. He'll sit next to Sam Ramsay with No. 33 and Sam Philp with No. 34 in the locker room.

Josh Honey, schoolmate and now teammate to Ramsay, was given the No. 36 jumper and another rookie, Fraser Phillips will wear No. 39.
