Mike Tomlin has said that the Pittsburgh Steelers must work on getting more turnovers.

The AFC North side, who are yet to win in 2013, are the only team in the NFL without an interception or fumble recovery.

The head coach told reporters: "We have to do a better job of preserving the ball. We worked hard at that over the last week, and getting the ball, we've yet to get a turnover. We acknowledge that.

"Even though we're not practising in pads, I think that ball security and getting to the football on defense are things that you can practise, regardless of circumstance. From a ball security standpoint, it's mechanics, the points of pressure on the ball and making it as a point of emphasis.

"Defensively, tackling, as big of a part of tackling as anything is the approach and making sure that you have correct angles to the ball, you have bent knees and ankles. We have an opportunity to do that every time the ball is snapped."

The Steelers face the New York Jets this weekend.
