Nick Foles figures he's starting for the Eagles against the Dallas Cowboys

As far as Nick Foles knows, he is the Eagles' starting quarterback for Sunday's regular-season finale against the Dallas Cowboys, Foles said Thursday.

Foles said he hasn't been told anything by coaches, but he is taking the starting reps in practice, even though the team wrapped up the NFC's top playoff seeding with Monday night's shaky, splotchy 19-10 victory over the Oakland Raiders.

"I haven't been told otherwise, so my preparation stays the same. … Nothing's changed, I'm preparing to play the Cowboys," said Foles, who has started the last two games since Carson Wentz went down for the season on Dec. 10 with a torn left ACL. "I'm preparing to play the whole game."

Foles alarmed Eagles fans with a rocky evening against the Raiders. After an early touchdown drive, the offense struggled to a pair of field goals, both set up by Oakland turnovers.

"I think the big thing is, first and second down, it's real important to get completions, stay inside the chains," Foles said, when asked what he saw when he looked at the film. "I think we went to a lot of second-and-long, third-and-long. That puts you in you in tough positions."

He said this especially holds true in cold weather.

Foles said he plans to be more cognizant going forward of Alshon Jeffery's ability to make catches even when covered. Jeffery was targeted only twice in the Oakland game and was held without a catch for the first time since his rookie season of 2012.

"Alshon is a dynamic receiver who can make a lot of plays. I definitely need to target him more," Foles said.

Sunday's game is scheduled to start at 1 p.m., which might make conditions a little better than they were Monday night, but the forecast high is 24 degrees. Foles said Monday night's conditions weren't the cause of his struggles.

"The weather wasn't an issue. I personally didn't execute well enough," he said. "Looking back at the film there's things that I can do that I have done better, whether it was fundamentally, getting a little out of whack at times … being a little more accurate, giving our guys the opportunity to make catches … that's all correctable, and that's something I'm working on this week."

Foles blamed dropped shotgun snaps on trying to read coverages and catch the ball at the same time. "They rotate their safeties late, so you're trying to see exactly what coverage [they're in] and what they're doing. Those are on me," he said.

There have been hints that the Eagles will activate rookie cornerback Sidney Jones by Jan. 3, when they have to make a decision on whether to do that or place him on injured reserve, but for the second day in a row, Jones said he was too busy to discuss the matter. … Brandon Graham (ankle) was the only Eagle who didn't participate in Thursday's walk-through practice.
