Carlton and Essendon are set to engage in a trade for the first time since 2003, with Blues ruckman Andrew Phillips set to become a Bomber over the next 48 hours.
Phillips was handed a one-year deal from the Blues for 2020, although the 28-year-old is "leaning towards" joining Essendon according to AFL.com.au, with the Blues looking to bring in Hawthorn back-up Marc Pittonet.
The trade would be the first one in 16 years between the two clubs, since Justin Murphy swapped navy blue for red and black in 2003.
Cory McGrath and Matthew Allan went from Essendon to Carlton that same season, although no player has switched directly between the clubs since.
Phillips' acquisition would mean Zac Clarke's spot on Essendon's list is in danger, given the Bomber doesn't have a contract for 2020 as it stands.
Sam Draper looks set to be Essendon's main reserve, given he recently signed a four-year deal despite not playing an AFL game.
