The 49ers today placed Aldon Smith on the reserve non-football injury list a designation that allows the troubled outside linebacker to seek treatment immediately. Smith was arrested early Friday morning for DUI and marijuana possession after crashing his car into a San Jose front yard. "Aldon Smith is taking a leave of absence to address a personal matter" said 49ers general manager Trent Baalke in a statement. "The 49ers organization both respects and supports Aldon's decision and commends him for taking responsibility for his actions. The long-term well-being of our players is paramount and we will stand by Aldon as he works toward addressing this issue. Due to the private nature of the matter we will have no further comment." Said Smith in a statement: "I am taking a leave of absence to address my health. I am sorry that I have affected my team my family and the organization. I will do everything in my power to handle this situation the best way possible. I appreciate the support of the 49ers and our fans."
