Essendon coach Brad Scott believes the "best case" has been put to keep Sam Draper, insisting the Bombers will continue to play two rucks.
Draper (achilles) and Nick Bryan (knee), who has recommitted to Essendon until the end of 2027, have been sidelined for the majority of this season.
But before their injuries in consecutive weeks, Draper and Bryan were playing in the same team.
"The evidence at the start of the year was very clear ... they were both playing career-best football together. We've been really clear in terms of we'd like to have that ruck partnership into the future," Scott said.
"The indication with changes to the sub rule only strengthens that case to play two rucks."
