Riding a three-game losing streak, the New York Giants decided Friday to insert Aaron Rouse into the starting lineup at safety for Sunday's game against the San Diego Chargers. Rouse will replace beleaguered veteran C.C. Brown, who has been beaten twice on deep passes for touchdowns during the losing streak. Brown missed a defensive audible in last Sunday's 40-17 loss to the Philadelphia Eagles, allowing DeSean Jackson to score on a 54-yard pass play late in the first half.
