ESPN’s Len Pasquarelli reports that injured San Francisco 49ers quarterback Alex Smith is scheduled to go through some light throwing drills the next two days and doctors will then re-evaluate him by the end of the week. The drills are being used by the 49ers to reach some clarity about the condition of Smith’s shoulder and forearm. The 23-year old Smith originally suffered a sperated shoulder on September 30th at home against the Seattle Seahawks and has missed the past three games after re-agravating the injury on November 12th against the Seahawks in Seattle. He has not thrown a pass since November 18th. Surgery remains an option for Smith, who told Bay Area reporters last week that he still has problems raising his right arm above his shoulder.
