Chisora has also expressed a desire in who he wants to fight last, with Dillian Whyte and Francis Ngannou both mentioned by the former heavyweight champion.
Chisora also gave heavyweight king Oleksandr Usyk - in his first fight in boxing's top division - a torrid team before eventually losing via unanimous decision.
However, the fight has now become an eliminator for the IBF heavyweight title - meaning the winner will be in line for a world title shot.
Chisora had also expressed an interest to end his career with a trilogy fight against old rival Whyte.
Should Chisora beat Wallin, a third title fight would be an incredible and fitting end to a storied career.
