Posted by ESPN.com's Pat Yasinskas.

Doug Plank will join the coaching staff of the Atlanta Falcons, two sources told ESPN.com Tuesday afternoon. Team officials confirmed the move later Thursday evening and said Plank's title will be coaching assistant.

Plank, 55, has spent the last three years as head coach of the Arena Football League's Georgia Force, a team also owned by Falcons owner Arthur Blank. A team official said Plank's role will be to help with special projects for offfense, defense and special teams. The Falcons said Plank will remain head coach of the Force, which plays a spring season.

Plank spent eight years playing for the Chicago Bears and his jersey number gave coordinator Buddy Ryan's storied 46 Defense its name.
