According to Birkett, Lang has told people close to him he “definitely” has played his last game, and an announcement could come as soon as Friday.
Lang had dealt with a number of injured in recent years and was limited to appearing in just six games last year, due to a neck injury.
There hasn’t been any reported interest in Lang since he was released by the Lions, but indications have been that he’s likely to call it a career.
Lang, 31, is a former fourth-round pick of the Packers back in 2009. He has played out his four-year, $20.8 million contract before agreeing to a three-year, $28.5 million contract from the Lions with $19 million fully guaranteed with the Lions in 2017.
Lang was set to make a base salary of $8.25 million for the 2019 season when the Lions released him a few weeks ago.
In 2018, Lang appeared in six games for the Lions.
