The Panthers are preparing for their third preseason game, and they’ll have an extra arm on the depth chart to see them through the schedule.

Carolina Panthers quarterback Andy Dalton injured his right elbow on Saturday and did not return in the team's preseason game against the Houston Texans. After the game, coach Dave Cannales said it appears to be a right elbow sprain and he will be evaluated tomorrow. Canales said Dalton told him he was fine.

The Carolina Panthers plan to sign free-agent quarterback Bryce Perkins "this week," according to Darin Gantt of the team's official website.
