Jim Caldwell is adding some familiar faces to his staff for training camp.
The Detroit Lions announced four interns as part of the Bill Walsh Minority Coaching Fellowship: Archie Collins (cornerbacks), Quinn Gray (quarterbacks), Kefense Hynson (receivers) and former Michigan standout Cato June (secondary).
June is the most recognizable name of the bunch and is also the coach at Anacostia High School in Washington, D.C. He has ties to Caldwell, having played in Indianapolis when Caldwell was on staff there. He also played at Michigan under defensive coordinator Teryl Austin.
Collins also has ties to the state of Michigan, having played at Michigan State. He played high school football at Detroit powerhouse Cass Tech and is the defensive backs coach at Central Michigan.
Gray played for the Colts -- with Caldwell on staff -- in 2008 and went to Florida A&M.
Hynson has spent time with four other NFL teams as part of the fellowship: Seattle in 2008, Oakland in 2009, Kansas City in 2010 and Houston last season.
