Narrative:

Flying into ord from msp after diverting to msp (due ord closing due WX) earlier from a den to ord flight we encountered moderate turbulence. We were descending from 17000 ft to 13000 ft in smooth air. No WX indications on radar in our area, but could see radar WX indications beyond ord. We could see the lights of chicago and lights on the ground in front of us. Suddenly, we experienced a 1-2 second 0-1 negative 'G' sensation, followed by a 1-2 second 1 - 1 1/2 positive 'G' sensation, then light turbulence. On the captain's command, I seated the flight attendants by the PA and he put the seatbelt on. We then saw some green indication on the radar and the captain deviated slightly right and shortly we were in smooth air again. We received a call from the aft galley flight attendant that we had 4 passenger and 2 flight attendants injured and that they would require medical attention when we got on the ground, dispatch was notified by ACARS of the ankle injuries and our request for medical assistance. The balance of the flight was uneventful and medical assistance met us at the gate.
