Tim Boetsch will not be facing a former Strikeforce champion at UFC 166.

Instead, “The Barbarian” gets CB Dollaway, as Rockhold has suffered a knee injury.

The bout is set for October 19 from Houston. It will be the main fight on the FOX Sports 1 prelims.

Boetsch (16-6) has won seven of his 12 UFC bouts, but is coming off a pair of losses. He had won four straight prior to his recent setbacks.

Dollaway (13-4) is coming off two wins in a row, including a recent “Fight of the Night” performance over Daniel Sarafian. He is 7-4 and a former Ultimate Fighter runner-up.

Other matches include Cain Velasquez vs. Junior dos Santos for the UFC heavyweight title and Daniel Cormier vs. Roy Nelson.
