New York ( CNN ) -- The British tourist who was struck by a New York City taxi after it jumped a curb had her left leg amputated below the knee , hospital officials said Thursday . Sian Green , 23 , was at 49th Street and Sixth Avenue -- home to Rockefeller Center and near Radio City Music Hall and Saks Fifth Avenue -- Tuesday morning when she and a bicyclist were both hit by the cab after the driver swerved onto the curb , authorities said . Given the condition of the lower leg , `` replantation was not an option , '' according to Dr. Spiros G. Frangos of Bellevue Hospital . Green 's right leg sustained multiple injuries but will likely regain most functionality with time and physical therapy , the trauma surgeon said in a statement . Green 's parents released a statement on Thursday , expressing their gratitude to all those that helped during this `` difficult time . '' `` We hope Sian will soon be on her way to recovery and will be able to personally thank all the kind people of New York City , '' they said . TV 's Dr. Mehmet Oz , host of `` The Dr. Oz Show , '' was nearby at the time of the accident and rushed over to assist , according to show rep Tim Sullivan . A good Samaritan walking by also aided Green . `` David Justino , a plumber from New York , took action , removing his belt and using it as a tourniquet , '' Oz said in a Facebook post . As of Thursday , the cab driver did not face criminal charges , police said . CNN 's Erinn Cawthon contributed to this report .
