Adelaide key defender Nick Murray will wear the famous No.9, taking over from former captain Rory Sloane.
Murray previously wore No.28 but switched it out following Sloane's retirement.
The No.9 holds significance at the Crows, with club legend Tyson Edwards also donning the single-digit number, playing 292 matches for the West Lakes club.
Taking Murray's former No.28 is recruit Alex Neal-Bullen, who crossed from Melbourne in the recent trade period.
Ironically, the Crows gave up Pick 28 for Neal-Bullen.
The number the former Demon will wear has a long history of ex-players, namely Kane Johnson (104 games), Bernie Vince (10) and Caam Ellis-Yolmen (39).
GWS pair James Peatling (No.25) and Isaac Cumming (No.44) were also handed their new numbers.
Peatling's new number was vacated by Ned McHenry, who was delisted by the club last month.
Crows fullback Ben Rutten also played 229 games in it.
As for Cumming's No.44, fellow key defender Nathan Bock wore it for 113 games, while Peter Caven (1996-2000) and Lachlan Gollant (2020-2024) held it for some time.
New draftees Sid Draper and Tyler Welsh were welcomed to their new club with very familiar numbers.
Welsh will follow in his father's footsteps, donning the No.17.
Scott Welsh wore the number for 129 games before handing it to Bernie Vince in 2008.
Will Hamill sported the number most recently but joined McHenry as one of the delistings after the 2024 season.
As for Draper, he was handed No.34, which club legend Ben Hart donned for 311 games and 15 years.
Recently departed swingman Elliott Himmelberg vacated the number when he joined Gold Coast as a free agent.
