The Panthers hit the practice field for the first time in Training Camp on Wednesday afternoon. Both Sam Darnold and Baker Mayfield evenly split the reps during 7-on-7 with Darnold working with the first team and Mayfield working with the second. Panthers head coach Matt Rhule said that the two would flip units on Thursday as he tries to gauge which will lead his team out of the tunnel Week 1 vs Cleveland. Meanwhile, Matt Corral and PJ Walker only received three snaps a piece. Is this what's to be expected moving forward? How might this impact Corral's development?The Panthers entered camp with Shaq Thompson as the lone player on the Physically Unable to Perform, or PUP, list. That list grew as second-year corner Jaycee Horn was added after suffering from soreness in his previous injured foot. Horn wasn't the only corner absent as veteran Rashaan Melvin retired on Wednesday. Should there be a concern over Horn's nagging injury?

Edge? DT?Support Us By Supporting Our Sponsors!DaveDownload the Dave app from the App store right now for an Extra Cash account and get up to 500 dollars instantly.
