UFC legend Georges St-Pierre signed his fight agreement to face current middleweight champ Michael Bisping at UFC 217 at Madison Square Garden in New York.
The on-again, off-again bout now appears written in stone to headline the Nov. 4 card.
St-Pierre was recently set to face Tyron Woodley, but UFC president Dana White pulled that fight after the latter's uninspiring win at UFC 214, awarding it back to Bisping.
Bisping hasn't fought since successfully defending his title for the first time against Dan Henderson in October. St-Pierre has been out of action since he stepped away from the sport in November 2013.
