Smith (groin) is questionable for Sunday's game against the Giants, Darin Gantt of the Panthers' official site reports.
Smith was a late addition to the injury report after missing practice entirely Friday, but coach Matt Rhule described Smith as on the "positive" side of questionable, per David Newton of ESPN. His absence would be significant because Smith played a starting role in Carolina's season opener and was expected to return punts this week. If Smith sits out Sunday, Laviska Shenault or DJ Moore would be the leading candidates to be the Panthers' punt returner, while Terrace Marshall or Rashard Higgins could step up as the No. 3 receiver.
