EDGE Analysis

Tremble underwent back surgery in May and opened camp on the active/PUP list. The fifth-year tight end has been increasing his workload and "appears to be trending in a good direction," per Newton. It remains unclear, however, if Tremble will be ready to play in Week 1 of the regular season.
