"Initially they were hoping to save the leg, but as the days went on it became apparent there was too much structural damage," Richardson said in a phone interview with The Associated Press. Green also will need a surgery to repair damage to a suborbital bone in his face. He has a cut about 6 inches long on the left side of his head "that's troublesome."
The surgery is set for Monday and comes a week after Green's brother and girlfriend were killed in the accident .
Kevin Richardson told The Associated Press that doctors had hoped Green could keep the leg, but there was too much damage. Green, 50, hopes to someday make a return to the golf course with the help of a prosthetic limb.
Green's brother and caddie, William Y. Green, and Jean Marie Hodgin were killed in the wreck.
Authorities say the right front tire on Ken Green's recreational vehicle blew out on Interstate 20 near Hickory, Mississippi. The RV went down a steep embankment and hit a tree.
Mississippi Department of Public Safety spokesman Jon Kalahar said Ken Green was not wearing his seat belt..
Green, a five-time winner on the PGA Tour from Danbury, turned pro in 1980. He has played on the Champions Tour the last two seasons.
His final years on the PGA Tour were marred by mental illness that that made it difficult for Green to concentrate while playing and led him to the verge of suicide. Recently, Green has begun speaking publicly about his ordeal. ctxt_ad_interface = 'http://cm.npc-scripps.overture.com/js_1_0/'; ctxt_ad_width = 420 ; ctxt_ad_height = 150; ctxt_ad_source = 'npc_scripps_tcpalm_t2_ctxt'; ctxt_ad_config = '7894763060'; ctxt_ad_id = 'sports'; ctxt_ad_type = 'sports'; ctxt_ad_url = window.location.href ; ctxt_css_url = 'http://media.scrippsnewspapers.com/yahoo/yahoo_cm.css' ;
