Smith caught two of three targets for 21 yards prior to exiting with a shoulder injury in Friday night's 34-9 preseason win over the Steelers.
Smith was forced to leave after making a catch during the fourth quarter. Afterward, coach Matt Rhule said Smith's injury seemed "significant," Joseph Person of The Athletic reports. Following a promising preseason run, that issue could stunt the rookie sixth-rounder Smith's availability and open a roster spot at the bottom of Carolina's receiving corps.
