Tommy Tremble Injury: Progressing well in recovery

Tremble (back) ran routes on the side during training camp Friday, David Newton of ESPN.com reports.

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.
