T.J. Lang's career in Green Bay is officially in the rearview mirror.
The 29-year old coming off of a Pro Bowl season is heading to Detroit, Michigan where he grew up to play with the NFC North rival Lions.
Rob Demovsky contributed to the report of Lang's departure early Sunday morning.
"Offensive lineman T.J. Lang has agreed to a three-year contract with the Detroit Lions, his agent announced Sunday."
Lang was a fourth-round selection under general manager Ted Thompson in the 2009 NFL Draft and ultimately swapped between the left and right tackle position before sticking to right guard in 2013 where he would soon finish his career with the Packers.
