Narrative:

On arrival we were notified by dispatch that there was moderate turbulence from 15000 ft through 10000 ft; 10 mi west of den. We were approximately 30 mi west of denver descending through 17000 ft. We suddenly got in a strong updraft followed by sudden moderate turbulence that lasted until we descended through 10000 ft. I told ATC about the sudden turbulence and he responded that he had not had any reports of it at that high an altitude. Aircraft were on the arrival ahead of us and had apparently not gone through it. The passenger were seated; but the flight attendants were not. 2 flight attendants were injured. We were met by in-flight supervision and paramedics. When we left the airplane; they were deciding if they would go to the hospital.
