PHILADELPHIA -- Eagles quarterback Carson Wentz will sit out practice Wednesday with what coach Doug Pederson described as back “soreness” and “tightness.”

Pederson would not commit to Wentz playing Sunday against the Los Angeles Rams.

“We’re going to rest him and continue to evaluate him and make sure he’s good,” Pederson said.

This isn’t the first time this season that Wentz has appeared on the injury report because of his back. He was a limited participant on consecutive Wednesdays in late October, but this marks the first time he has missed a practice this season.

“Sometimes he just gets a little sore, a little tight, and so we’re just going to rest him today and evaluate him further,” Pederson said.

It was one year ago Monday that Wentz tore the ACL and LCL in his left knee against the Rams. The main storyline heading into this week was Wentz’s return to the L.A. Coliseum for the first time since the injury for a rematch against Jared Goff, who went first overall in the 2016 NFL draft, one slot ahead of Wentz.

Now it’s unclear if he’ll be able to play. If he can’t, Super Bowl MVP Nick Foles will take the reins as the 6-7 Eagles try to keep their playoff hopes alive against the 11-2 Rams.

“We’re going to focus on today, get through today,” Pederson said when asked if there’s a chance Wentz misses this game, “and see where he is at the end of the day.”
