The Eagles have an interview scheduled with Bengals offensive coordinator Jay Gruden on Monday.
Owner Jeffrey Lurie, general manager Howie Roseman and president Don Smolenski interviewed former Chicago Bears Lovie Smith on Thursday. They previously met with Atlanta assistants Mike Nolan and Keith Armstrong and Denver offensive coordinator Mike McCoy.
Notre Dame's Brian Kelly met with the Eagles on Tuesday, a day after the Fighting Irish lost 42-14 to Alabama BCS national championship game. But Kelly said Saturday that he is staying at Notre Dame.
Penn State's Bill O'Brien and Oregon's Chip Kelly interviewed with Philadelphia last week, but also chose to remain at their schools.
"There is no question we spent a considerable amount of time and effort looking at who we thought were the best collegiate candidates for our head coaching job," the Eagles said Saturday in a statement. "We did so knowing that there was a remote chance that these coaches would leave their current posts. We understood that going into the process, but we wanted to leave no stone unturned while trying to find the best head coach for the Philadelphia Eagles.
"We have no regrets about the effort we made in that direction and we will continue to proceed as planned in our search."
