Tremble (hamstring/back) practiced in a limited capacity Thursday, Darin Gantt of the Panthers' official site reports.
Tremble has been dealing with a hamstring issue since the early days of training camp in late July, while a back injury showed up on Carolina's Week 1 practice report. They combined to sideline him this past Sunday at New Orleans, but with back-to-back capped sessions under his belt, the tight end seems to be positioning himself to make his season debut this weekend. Ultimately, Friday's report will reveal whether or not he has a designation ahead of Sunday's game against the Chargers.
