Saunders was elevated from the Panthers' practice squad Saturday, Darin Gantt of the team's official website reports.
The wide receiver last appeared in a game in Week 17, failing to draw a target on five offensive snaps. Saunders' role will likely be similar in Week 18 against the Buccaneers as he'll operate as an extreme depth option behind the likes of DJ Moore and Robby Anderson (questionable, quad), among others.
