Luke Hodge will don the number two at Brisbane.
Hodge, after wearing 15 across a 305-game career at Hawthorn, will switch into the new number previously worn by Ryan Harwood for the 2018 season.
Hodge's previous number 15 is currently being worn by three-time best and fairest winner Dayne Zorko.
Number two has notably been worn by Chris Johnson, who played 274 games for the Lions.
Fellow recruit Charlie Cameron won't have to make a switch, opting to stay in the vacant number 23 he wore at Adelaide.
The number has been worn by triple premiership defender Justin Leppitsch, as well as Fitzroy greats Norm Brown and Bob Henderson.
Youngster Jacob Allison has also made a jumper switch, moving from the number 37 to number 19, last worn by the delisted Josh Clayton.
