ARLINGTON, Texas -- Mark Sanchez seemed to be fully in control of the Eagles offense Thursday against the Dallas Cowboys, even when his control was called into question.

Sanchez got into an on-field shouting match with wide receiver Riley Cooper in the fourth quarter of the Philadelphia Eagles' 33-10 victory. Cooper had lined up in the wrong spot on a third-down play, and Sanchez had to call a timeout to correct the mistake.

The two were seen on television shouting at each other after the incident.

“We’re a family and families get heated and get upset and that’s the way it goes,” Sanchez said after the game. “Both of us had something to say. We said it and that was it.”

Cooper was not seen in the Eagles’ locker room after the game.

On the field, Sanchez completed 20 of 29 passes for 217 yards and a touchdown. He also ran the ball seven times for 28 yards as the zone-read reappeared in the Eagles’ offense after going missing in last week’s win over Tennessee.

“(The Cowboys) were trying to bend the (defensive) end and tried to take away the back,” Kelly said. “Obviously, when they try to outnumber us, the quarterback can be a weapon at certain points of time during the game. We saw something from the sidelines and just knew that if they presented the same look, there’s an opportunity for us to pick up some yards.”

The Tennessee game was the first in Kelly’s tenure that saw the Eagles fail to run a single zone-read play. In his previous starts, according to ESPN Stats and Info, Sanchez ran a total of six zone-read plays for 34 yards. Against Dallas, the Eagles ran a total of 21 zone-read plays for 135 yards and two touchdowns -- one by Sanchez, one by LeSean McCoy.

The strong running game also made Sanchez’s use of play-action effective. Sanchez completed 6 of 9 passes for 61 yards and a touchdown off play-action fakes.

With Nick Foles scheduled to have a CT scan Friday on his collarbone, the Eagles should have a clearer timetable on his possible return. The scan should show how far along the bone is in the healing process. Kelly has refused to answer questions about his intentions when Foles is cleared to return.

Last season, Foles began to play well while Michael Vick was recovering from a hamstring injury. When Vick returned, Foles kept the starting job.
