"We'll go balls-out with Dez," owner and general manager Jerry Jones said Tuesday on 105.3 The Fan in Dallas.
Bryant missed five games recovering from a broken foot suffered in the season opener and has played through knee and ankle injuries since Nov. 8. In eight games, he has caught 27 passes for 351 yards and two touchdowns.
Jones puts Bryant's lack of success this season on missing the offseason program with a contract dispute and missing half of the training camp practices and the four preseason games with a hamstring injury.
"I'm not so sure the foot is an issue apart from the fact that it limited him very early in the season and training camp, and of course the way [we] were involved in negotiations during the spring," Jones said. "In my mind, it is completely related to lack of practice, repetition.
"Dez is a passionate player. He's a passionate practice player. But he just hasn't had enough of it to cope with what we need him to be doing right now."
Bryant caught one pass for 9 yards in Sunday's loss to the Green Bay Packers. He dropped two passes and had another pass deflect off his hands for an interception on the Cowboys' first drive of the game.
After the game Bryant said he let the rainy weather affect him, changing his gloves three times during the game.
"Now, that was an aberration, in my mind, in Green Bay," Jones said. "I don't know if it was the slick ball. I don't know that anybody does. But whatever it was, we shouldn't expect to have that kind of result or that kind of performance from Dez or certain other areas of the team."
