Narrative:

We received a SIGMET on the printer from dispatch and mapped the area on secondary flight plan page. We were west of the enclosed area; but were hearing reports of light to moderate chop between FL350 and FL320. We turned on seatbelt sign and first officer made an announcement. I called both ends of the cabin simultaneously to alert to chop in descent and told them to pack up. We were given [pilot's discretion] to FL200 and upon pulling for open descent we encountered light turbulence. I used the PA to seat the flight attendants before descending; passing FL350; and prior to any moderate chop. We had about 2 minutes of light to moderate chop and descended into smooth air for the duration of the flight. After landing; we debriefed with the lead flight attendant about an altercation with a customer service agent prior to departure and were not told of any injuries from the chop on descent. Upon descent on a subsequent leg; we were alerted via ACARS to call the duty manager and only after landing did we learn that a flight attendant on the turbulence flight suffered an injury.
