Tinker joined the cast of Friday Night Lights in September 2009 playing Dallas Tinker, a small town football player. He had initially gone to the shoot to support two of his friends who had landed work as extras on the show, taking the bus with them from Houston to Austin. He met the show's executive producer, Peter Berg, who was directing the episode being filmed, and unexpectedly found himself acting in a scene with two of the show's regulars. The series was filmed using three cameras, without rehearsal and without extensive blocking, and Tinker later recalled, "It was cameras up, let's go. I did it, and he liked it." Two days later, the plans for the show's fourth season were being adjusted to include a new character, Dallas. He was a recurring character for that season, and for the final, fifth one.
