Chris Leben will return to action this December, a month after his suspension ends.
Leben was suspended last November for failing a drug test. He will face Karlos Vemola at UFC 155, UFC officials announced on Wednesday.
Leben (22-8) has posted a 12-7 record inside the Octagon, but is coming off a loss to Mark Munoz. The drug test came after the Munoz defeat, and he was given a year-long suspension.
Vemola (9-3) is also coming off a defeat, as he was topped by Francis Carmont. Vemola is 2-3 with the UFC.
