Jason Garrett was angry last week after watching the Dallas Cowboys commit six turnovers in losing 12-7 to the Arizona Cardinals.

“Inexcusable” he said of the sloppy performance.

On Saturday night the coach's tough talk turned into action.

The Cowboys entered their game with the Cincinnati Bengals determined to give DeMarco Murray his heaviest workload of the preseason. But after the tailback fumbled in the first quarter inside the Dallas 10-yard line on his third carry Garrett made a gutsy but necessary move.

Right tackle Jermey Parnell recovered for the Cowboys but that didn't stop Garrett from sending Phillip Tanner into the game the next time they had possession and keeping Murray on the sideline until after halftime.

Playing with a chip on his shoulder after the embarrassing benching the former Oklahoma standout rushed for 45 yards on eight carries in the third quarter to finish with 51 yards on 12 attempts. He also scored on a 7-yard pass from Kyle Orton slipping past four defenders inside the 5-yard line.

“The ball cannot be on the ground” said Garrett explaining why he yanked Murray. “He understood why. We talked to him about it and I thought he responded well to it.”

The benching came with the blessing of Jerry Jones.

“There is no question we had a little in-house resolve about what we would do if we should turn the ball over” the owner said. “I think (Murray) came back with resolve. I still think he had an attitude after he finished that third quarter. But I think Jason's making a point.

“The good news is that with Murray he made it with somebody who can take it and you saw the reaction of all the team.”

Murray stood on the sideline with his helmet on and his hands on his hips while watching Tanner. After Murray scored he received a hearty welcome back to the sideline from Garrett and his teammates.

“That's Murray all day” Dez Bryant said. “He brings that spark to this offense. You just love him.”

Murray declined to talk to reporters but Garrett had plenty to say.
