Childress, who spent last season as the offensive coordinator for the Cleveland Browns, will be the Chiefs’ spread game analyst and work on special projects.
He spent five years as the Minnesota head coach (2006-10), a stint that included two division titles (2008-09). The team was 12-4 in 2009.
Childress previously spent seven seasons (1999-2005) with the Philadelphia Eagles, where he worked with Reid, the new Chiefs head coach. Childress coached the quarterbacks for the first three years and spent the final four as offensive coordinator.
The hire was announced Thursday.
PATRIOTS: signed free agent wide receiver Michael Jenkins.
In his ninth season, Jenkins caught 40 passes for 447 yards and two touchdowns with the Minnesota Vikings last year. He joined them in 2011 after seven seasons with the Atlanta Falcons, who drafted him in the first round in 2004 out of Ohio State.
Jenkins has 354 catches for 4,427 yards and 25 touchdowns in 130 games, including 79 starts. The Vikings released him March 5.
The Patriots lost their top two receivers from last season when Wes Welker, who had 118 catches, signed with the Denver Broncos, and Brandon Lloyd, who had 74 receptions, was released. They’ve added free agents Danny Amendola from the St. Louis Rams and Donald Jones from the Buffalo Bills.
