UFC 158 Fight Card Adds Antonio Carvalho vs. Darren Elkins and Mitch Gagnon vs. Issei Tamura | MMAWeekly.com

The UFC 158 fight card grew by two additional bouts on Monday.

UFC Canadian officials announced that Antonio Carvalho would square off with Darren Elkins in a featherweight bout, while also adding a bantamweight battle between Mitch Gagnon and Issei Tamura.

The bouts are two of the rare non-welterweight match-ups that grace the UFC 158 fight card that features UFC welterweight champion Georges St-Pierre putting his belt on the line against Nick Diaz.
