Jones said Witten obviously stayed in Raiders game one play too long but refused to second guess

Cowboys owner Jerry Jones doens't even want to consider possibility of injured tight end Jason Witten not being ready for the season opener.

Witten is out for the rest of the preseason with a lacerated spleen and could be sidelined for the Sept. 5 season opener against the Giants.

 Jones, who said he held his breath when Witten took the blindside hit in the game, said his focus is on getting him healthy, not how long he will be out. 

I haven’t thought about it at all. We’re basically more interested in him resting this week and getting that thing healed back.I really don’t have any timeline. All I know is he’s going to be out here for a few days while that thing actually heals and we don’t know how fast that will be. We don’t know at all. I’ve heard timeframes all over the map. All I can go is by what I’m told. We’ll see how it heals."

Jones also refused to second guess the decision to have Witten go three series in a meaningless preseason opener against the Raiders when the offense was already challenged to play behind a patch work offensive line.

"That’s second guessing," Jones said. "He certainly went one play too long, from that standpoint, if you looked at it that way. But I don’t at all second guess that."
