Top Rank vice president Carl Moretti revealed earlier this month that an agreement had been reached for the former world heavyweight champion to step into the ring with the 28-year-old Wallin.
It was confirmed on Tuesday that unbeaten Swede Wallin (20-0) will get a chance to claim the Briton's lineal title in Nevada next month.
Fury brutally knocked Tom Schwarz out at the same venue in June and will be a strong favourite to add another victory to his record, which shows 28 wins and a draw.
