DeSean Jackson is no stranger to goal-line blunders. His mistakes usually involve prematurely celebrating before crossing over the goal line, but in the Redskins' playoff game against the Packers on Sunday, Jackson's error in judgement differed.

In the first quarter, Jackson caught a pass from Kirk Cousins and headed to the corner of the end zone. But instead of extending for the goal line before he was pushed out of bounds, Jackson simply kept the ball tucked close to his body.

His lack of awareness cost the Redskins four points, as they settled for a field goal instead of scoring a touchdown.

Even Jackson acknowledged his error.

As previously mentioned, this is hardly Jackson's first goal-line mistake.

The only positive? At least Jackson's blunder didn't involve a fumble this time.
