A month before the UFC's return to Houston, there has been a change in a key middleweight bout on the card.

A knee injury has forced Luke Rockhold (10-2 MMA, 0-1 UFC) out of his fight against Tim Boetsch (16-6 MMA, 7-5 UFC). Rockhold will be replaced in the bout by C.B. Dollaway (13-4 MMA, 7-4 UFC). UFC officials announced the change on Wednesday's edition of "UFC Tonight" on FOX Sports 1.

UFC 166 takes place Oct. 19 at Toyota Center in Houston. The main card, which features a heavyweight title fight and rubber match between champ Cain Velasquez and former titleholder Junior dos Santos, airs on pay-per-view following preliminary-card bouts on FOX Sports 1 and Facebook.
