PHILADELPHIA (973espn.com) - Josh McDaniels left the Indianapolis Colts at the altar and that means the Colts have to move on to Plan B, which could include Eagles offensive coordinator Frank Reich.

Reich started his NFL coaching career in Indianapolis from 2008-11 in various capacities, starting as an offensive assistant before stints as the Colts' QB coach and then WR coach.

The wide-ranging experience Reich gathered in Indy put him on the fast track to being an OC and after a year as a WR coach in Arizona he was back to coaching QBs in San Diego before being elevated to OC by the Chargers in 2014.

Reich then arrived in Philadelphia as Doug Pederson's right-hand man and is now on the Colts' new short list.

The Eagles, of course, beat New England in Super Bowl LII on Sunday and McDaniels, the Pats' OC, walked back on an agreement to become the Colts next head coach.

Indianapolis even announced the move on Tuesday before McDaniels changed his mind after talking to Robert Kraft while ostensibly set to clean out his office in Foxborough.

Buffalo defensive coordinator Leslie Frazier, a former head coach in Minnesota, is also believed to be high on Colts GM Chris Ballard's radar while news surfaced Wednesday afternoon that Saints assistant head/tight ends coach Dan Campbell, a former interim coach in Miami, will interview for the position Thursday.

Reich is set to talk with the Colts on Friday, an NFL source told 973espn.com.

If Reich does get the job in Indianapolis that could pave the way for Eagles quarterbacks coach John DeFilippo to be promoted. Otherwise, the Vikings are believed to have a strong interest in making DeFilippo their new OC and are waiting to make a decision until they can interview him.

The Eagles blocked DeFillippo from taking the New York Jets OC last season but would not be able to do that kind of thing this time around because he will be out of contract.
