The Detroit Lions were not chosen to be featured on HBO’s Hard Knocks this year, but that does not mean fans will not be able to get an inside look to the team's training camp this season.
Inside the Den, the Lions own self-made version of Hard Knocks returned on Tuesday, and it featured the opening days of the team’s camp. Watch quarterback Matthew Stafford work through the first days of practice with new quarterback coach Sean Ryan. See other stars and youngsters as they work through the team’s return to football.
