Received a phone call concerning damage found on Aircraft X.  I was Pilot flying and First Officer on the aircraft that morning.  I did not see any damage to scimitar winglets on my walk around.  Taxi out; takeoff; flight; landing; and parking were all uneventful and at no time did the winglets come close to objects that would cause damage.
