SAN DIEGO (AP) - Like backup quarterbacks? Then the Dallas Cowboys-San Diego Chargers exhibition opener Thursday night is one to watch.
With Tony Romo sitting out to rest his surgically repaired back, Brandon Weeden will get the start for the Cowboys.
Philip Rivers likely will take a seat after the opening series, allowing Kellen Clemens to make his Chargers debut after Charlie Whitehurst took his clipboard and signed with Tennessee.
Weeden got all the first-team reps during offseason workouts and more first-team work in training camp with Romo essentially sitting out every third practice.
