The Carolina Panthers lost their second preseason game, at Houston on Saturday. Carolina has now been outscored 50-13 in the preseason.

Compounding the issue, backup quarterback Andy Dalton left the game with an injury, forcing third-string QB Jake Plummer into extended action. Plummer showed some promise, completing 10 of 14 passes, but also threw an interception—highlighting both the potential and growing pains in the depth chart at quarterback.

According to an analysis by Yardbarker, Carolina's backup QB situation gets a 3 out of 5 rating.
