Scheffler told The Associated Press on Wednesday he made the choice because he had three concussions over the past four years. Analysis: He had 258 receptions for 3,207 yards and 22 touchdowns in his eight-year career. The Detroit Lions released Scheffler in October. He later had workouts with Chicago and Kansas City and says there was "moderate" interest in him as a free agent this offseason.
