Inflight Event / Encounter Wake Vortex Encounter
Flight Crew Took Evasive Action; General Physical Injury / Incapacitation
Procedure; Environment - Non Weather Related
During descent encountered moderate wake turbulence following a B737-900. Fortunately seat belt sign was on and no injury to the passengers; however it did throw flight attendant into her aft jump seat area. We immediately contacted the all flight attendants after the event and learned she had injury to her shoulder and neck area; but not critical and no need for medical priority handling. Within several minutes we encountered a second event of light wake turbulence behind the same airplane. At this point we elected to slow our airspeed to 210; creating greater spacing. Made comments to ATC for reference; based on TCAS we already had approximately 5 miles or greater of separation when this took place. Landed on Runway 26L without incident and the other aircraft arrived on Runway 26R.
