Weather
On descent encountered severe turbulence FL306 through approximately FL260. ATC cleared us from FL360 to FL280 told us there had been turbulence reported FL330 to FL300 but no specific area or intensity. Seat belt sign was on already so I tried to expedite through the altitudes we were warned of and descended at .76 Mach to 280 knots for turbulence penetration. Severe lasted about 2-3 minutes and we got clearance to continue descent to FL240; about FL260 it smoothed out. As soon as we were able we checked with the FAs and learned one was injured. [Advised ATC] and were given priority handling. EMTs met the plane and she and a passenger complaining of back pain were taken to the hospital.
