NASHVILLE, Tenn. (AP) — A person familiar with the situation says that the Tennessee Titans will start Joshua Dobbs at quarterback Thursday night against the Dallas Cowboys instead of rookie Malik Willis. The Titans' third-round pick out of Liberty, WIllis had been expected to make his fourth start with veteran Ryan Tannehill among eight declared out for this game. Instead, the Titans will start Dobbs, whom they signed off Detroit's practice squad Dec. 21, the person familiar with the decision told The Associated Press.
