Childress signed as an undrafted free agent by the New England Patriots out of college in 2005. He signed a short-term deal, participated in training camp and played well in preseason, both as a wide receiver and extra defensive back. Because of his hard work and determination to make the team he earned a spot on the New England Patriots' practice squad. Childress was activated for the last game of the 2005 season against the Miami Dolphins and played well in a losing effort, finishing with three catches for thirty two yards. Prior to the Patriots' 2006 season opener, the team released him, signed him to their practice squad, and then activated him again. After the opener, he was released, signed to the practice squad, and later activated on December 23. Childress spent all of the 2007 on the Patriots' practice squad.
