ST. LOUIS -- Donald Brown's Sunday afternoon in the Edward Jones Dome was brief, productive and painful. The Indianapolis Colts rookie running back needed only two carries to pile up a career-best 58 yards, then needed ice for his left shoulder. Brown did not return to the Colts' 42-6 win over the St. Louis Rams after spraining his shoulder on his final carry, a 13-yarder in the second quarter.
