ALLEN PARK — Tight end Tony Scheffler didn’t participate in the Organized Team Activities Thursday morning due to an irritated right foot which was in an orthopedic boot. Coach Jim Schwartz does not expect him to be out too long and said it was not serious.

Two new Lions were on the field who have been signed since last week’s workouts.

Safety C.C. Brown bring experience to the defensive backfield.

“He’s a guy who’s a really hard hitter and he’s still young,’’ Schwartz said of Brown who has five years of NFL experience and is 27 years old.

Also new to the group was tight end John Madsen who was signed this week.

“He’s a multidimensional tight end. He has some wide receiver in his background. He’s a guy who’s probably a little better pass receiver than blocker right now, but that’s OK because we use our tight ends in a lot of different roles,’’ Schwartz said of the 27-year-old Madsen.
