Foles has thrown nine interceptions and has had 12 total turnovers through the opening seven games so far, and he admits that he will have to work on making better calls.
"I'm the decision-maker on offense," Foles said, ESPN reports.
"I have the ball every single play. Yes, I have to do a better job. Words can't describe it. I have to go out here and keep working. It doesn't feel good at times. You have to keep working on fundamentals and on decision-making. I'm going to keep working, and I'm going to fix it."
Coach Chip Kelly has kept his faith in his signal-caller so far this season but Foles conceded that the pressure will be on him to perform against the Houston Texans on Sunday.
