Travis Lutter moved quickly through the quarter-finals when he defeated Scott Smith by rear-naked choke at 1:13 in the first round. On the semi-final episode, which aired on October 26, 2006, Travis Lutter defeated Pete Sell to move on to the finals set for November 11, 2006. At the finale of The Ultimate Fighter 4, Lutter defeated Patrick Côté with an armbar at 2:18 in the first round.

With this victory, Lutter became the challenger for Anderson Silva's Middleweight title. Lutter dedicated his victory on November 11 to the Wounded Warrior Project, an organization dedicated to support wounded U.S. servicemen.

On the day of the weigh-in, one day before the February 3, 2007 bout at UFC 67, Lutter failed to make weight. He weighed-in at 187 pounds on the first attempt, and 186.5 two hours later on his second attempt. Because of his failure to meet the required 185 pounds, his match with Silva was changed to a three-round, non-title bout. This upset many fans, and he was booed upon his entrance into the octagon. Lutter would go on to lose in the second round via submission due to elbows.
