PHILADELPHIA (973espn.com) - There will be no tap-dancing this week.

Doug Pederson announced Monday Nick Foles would again be the starter against the Houston Texans on Sunday as Carson Wentz continues to nurse a "stress injury" in his back. Wentz, though, will not be going on injured reserve, at lest not yet, according to the coach.

In theory that still puts Wentz in play for a Week 17 matchup with Washington and a potential playoff run if the Eagles are able to win out and reach the postseason. An NFL source has told 973espn.com, however, that Wentz is not expected back this season.

Foles performed admirably in Los Angeles on Sunday night as the Eagles upset the powerful Rams, 30-23, as a two-touchdown underdog, completing 24-of-31 passes for 270 yards with an 89.4 passer rating.

After the overtime loss in Dallas, Pederson explained they he met with offensive coordinator Mike Groh in an attempt to condense the offensive as a whole and "get back to the basics," a plan devised before the team knew it would be without Wentz against the Rams but one that likely helped Foles, who hasn't played since Week 2, get up to speed.

Pederson credited Groh, who has been much-maligned as the replacement for Frank Reich, for getting Foles comfortable by minimizing pre-snap motions and the offense humming as a whole against L.A., an effort which resulted in 381 total yards and three touchdowns on the ground.

"I don't know if I've said this, but after the Cowboy game, Mike and I, Mike Groh and I got together and we wanted to kind of condense the plan just a little bit for the guys," Pederson said. "We felt like we just kind of needed to get back to the basics just a little bit. So this was before, the Carson, Nick deal last week, we decided to go forward with that and put together a game plan that would be conducive for anybody, any of our quarterbacks.

"And so I think that's what you saw that came out of the game, which was a credit to Mike and putting the plan together like he did. Gave Nick, as we went through the week last week, every opportunity to comment on the game plan, if there were things he didn't like, just like we would with Carson. And there were a couple things, but for the most part, Foles felt comfortable with it. Didn't really have to change a whole lot, or at least go back to last season to pull anything from last year."
