Next month’s UFC 158 lineup is set, and it features a super-sized 13-fight lineup.

The event, which takes place March 16 at Montreal’s Bell Centre, features welterweight champion Georges St-Pierre (23-2 MMA, 17-2 UFC) vs. rival Nick Diaz (26-8 MMA, 7-5 UFC), in the pay-per-view.

The featured prelim pits against welterweight Patrick Cote (18-8 MMA, 5-8 UFC) vs. Strikeforce import Bobby Voelker (24-8 MMA, 0-0 UFC). It airs on FX following additional prelims on Facebook.

In all, eight fights are slated for the prelims.

In addition to St-Pierre vs. Diaz, the event features two significant welterweight bouts (following Rory MacDonald’s withdrawal and some card-shuffling): former interim champ Carlos Condit (28-6, 5-2) vs. Johny Hendricks (14-1 MMA, 9-1 UFC) and ex-Strikeforce champ Nate Marquardt (32-11-2 MMA, 10-4 UFC) vs. Jake Ellenberger (28-6 MMA, 7-2 UFC).
