FLAGSTAFF, Ariz. – Over 20 years ago, Brad Childress and Andy Reid were working under Larry Kentera at Northern Arizona University. On Sunday, they will face off in the NFL Wild Card round with Childress's Minnesota Vikings hosting Reid's Philadelphia Eagles.

Childress coached on the Northern Arizona staff with Reid in 1986, along with Eagles assistant head coach/offensive coordinator Marty Mornhinweg in 1988, and with Eagles TE coach Tom Melvin from 1986-87. Childress was offensive coordinator at Northern Arizona when Reid was hired by the school as an assistant coach.

Prior to taking over the Vikings, Childress spent seven seasons as an assistant under Reid before taking the Vikings' head coaching job in 2005. Childress' last four seasons in Philadelphia were spent as the team's offensive coordinator.

"I don't particularly relish playing those guys just from a personal standpoint," Childress said Monday. "He will give it his best shot and we will give it our best shot."

The Eagles clinched a playoff berth by defeating the Dallas Cowboys 44-6. The Vikings won the NFC North title when they beat the Giants 20-19 on a last-second field goal by Ryan Longwell.

Childress and Reid are among five former NAU assistants to have led NFL franchises as head coaches, joining former head coaches Mike Shanahan (Denver), Bill Callahan (Oakland) and Mornhinweg (Detroit).

Minnesota assistants Darrell Bevell (NAU Player, 1989), Jeff Imamura (NAU Assistant, 2000-02), Derek Mason (NAU Player, 1987-91) and Pat Morris (NAU Assistant, 1978) also have connections to the Mountain campus.
