Jerry Jones has said that the Dallas Cowboys need to put their recent disappointing December form behind them in a bid to reach the NFL playoffs this season.

Quarterback Tony Romo is 11-15 in the final month of the regular season in his career, while the Cowboys currently lead the NFC East but have the same record as the in-form Philadelphia Eagles.

The team's owner told KRLD-FM: "It's hard to build up in this time of the NFL. It's hard to build up enough edge to play at that level during December, so you better be moving or having your arrow going up rather than going down.

"We can't expect to be where we all want to be unless we play better than we've certainly played the last two years, and we've had a Tony Romo playing well, really the last two years and haven't gotten there.

"I've often said it is one of the biggest disappointments of my entire time to have Romo as quarterback and not be in better shape for the playoffs as we looked to his career. We need to change that."

The Cowboys have missed out on a place in the playoffs for the last three years.
