ARLINGTON — In a perfect world, the Cowboys hope Brandon Weeden has taken his final snaps in a game this season. The quarterback started and played four series, into the second quarter Thursday night against the Broncos in the preseason finale.The Cowboys produced only 98 yards and three points in Weeden’s 23 snaps, including one penalty, though Weeden didn’t have many key players around him. Left guard Ron Leary and fullback Tyler Clutts saw some action, but the Jason Wittens, Dez Bryants, Tyron Smiths and DeMarco Murrays cheered from the sideline."We had a hard time getting into a rhythm," Weeden said. "The most important thing is we were able to get 4 or 5 yards on some runs and put us in second-and-manageable. It gave us the ability to convert second down instead of third down, which we didn't do on the first drive. We did some good things with a lot of young guys in there that are playing positions they may not be familiar with. Overall, I thought everyone handled it pretty well. That's one of the difficult parts of this fourth preseason game."Weeden finished 6-of-12 for 75 yards and an interception. His passer rating was 35.1. "I thought Brandon did some good things," Cowboys coach Jason Garrett said. "He had that one interception on that naked where the guy came off the outside receiver and made a play on an out route on one of the inside receivers. Sometimes that's hard to see. He missed some throws, but he also made some good throws."Third quarterback Dustin Vaughan took over for Weeden.
