Before the Detroit Lions see what they have in Derrick Barnes, they want to see what they can get for Jamie Collins.
The Lions are exploring trade options for Collins, ESPN and NFL Network reported Wednesday, one day after coach Dan Campbell said Barnes "deserves a shot" at more playing time.
Collins, who missed practice for non-injury reasons Wednesday, struggled in Monday night's loss to the Green Bay Packers, when he allowed a receiving touchdown to Aaron Jones and appeared late diagnosing several plays.
Asked Tuesday about Collins' effort level, Campbell said he does not play with the same effort as fellow linebacker Alex Anzalone.
