The Ultimate Fighter: Team Carwin vs. Team Nelson is the sixteenth main installment of the Ultimate Fighting Championship (UFC)-produced reality television series The Ultimate Fighter. This season reverted to the taped format, after The Ultimate Fighter: Live's 12-week live format. The previous season saw the show be revamped. Prior seasons of the show were filmed in six weeks, edited and aired several months after filming was completed, whereas The Ultimate Fighter: Live was being filmed over thirteen weeks, featuring live fights. This season returned the old taped format, but stayed on Friday nights
