FLACCO STRIKES BACK: Quarterback Joe Flacco has struggled at times during practice the past couple of weeks and his sloppiest practice might have been Saturday, when he was intercepted four times in team drills. But Flacco responded with a sharp practice Sunday. In one drill inside the 10-yard line, he completed five of his eight attempts with one touchdown, but it should have been more. His receivers couldn't hang on to three of his throws, including two in the end zone. In the blitz period, he went 4-for-7 with two touchdowns and one pass for a first down. And in a late-game scenario at the end of practice, Flacco moved his offense into field-goal territory with five straight completions.
