Los Angeles Rams quarterback Matthew Stafford has been nearly unstoppable this season. His leads the league with 30 TD passes. On Sunday, he faces a Carolina Panthers secondary that could be missing three key players. Cornerback Jaycee Horn, who had two interceptions against San Francisco’s Brock Purdy on Monday night, is in the concussion protocol and backup Corey Thornton went on injured reserve with a broken leg this week. Also, safety Tre’Von Moehrig is facing a one-game suspension for punching 49ers wide receiver Jauan Jennings in the groin.
