Ben Henderson vs. Josh Thomson will headline the card at the United Center.
Viana (7-1) returns to the cage following the first official loss of his MMA career. The TUF: Brazil contestant dropped two weight classes after his 150-pound catchweight bout with John Teixeira at UFC 147. After an impressive knockout win over Reuben Duran in his bantamweight debut, "Wolverine" was dominated and finished by T.J. Dillashaw at UFC on FOX 7.
Hernandez signed a deal with the UFC after racking up a 13-4 MMA record with nine stoppage victories, but he failed to win in his Octagon debut at UFC Fight Night 28, when he was submitted by Lucas Martins in 70 seconds.
