Kevin Radke, the leading jockey at the 2003-2004 Golden Gate Fields meeting, suffered fractures to his left wrist and nose when he went down in the sixth race at Bay Meadows Wednesday. He'll be sidelined for six to eight weeks, according to an initial report.Radke was unseated when his mount, Reflected Lite, clipped heels with Terra Firma on the first turn of the one-mile turf race for 3-year-old fillies. "The fractured wrist has significant dislocation," reported Dr. David Seftel, track physician at Bay Meadows. "He also has compound fractures of the nose and will need nasal reconstruction. He definitely received a blow from a hoof and may have some other facial fractures."The rider was taken to Stanford Hospital in Palo Alto and was to have surgery Wednesday evening. "They'll put pins in his wrist and reconstruct his nose," said Seftel.Radke upset perennial riding champion Russell Baze when he won 88 races at the 109-day Golden Gate Fields meeting that concluded April 4. He is winless at Bay Meadows' 55-day spring session, which began on April 7. He went 0-for-18 during the opening week and had missed with three mounts Wednesday before going down in the sixth race.
