ALLEN PARK -- The Detroit Lions will hold their first practice of training camp on Friday morning. Here are five veterans who are on the roster bubble.
S Miles Killebrew
Hopes were high for him after a promising rookie season in 2016, but he faded from the rotation last year and not even the season-ending injury to Tavon Wilson could change that. Detroit opted to move Quandre Diggs back there instead, and he played so well that the move now appears to be permanent. With Wilson and Diggs both back, plus Glover Quin still doing his thing as one of the most consistent safeties in the game, Killebrew could struggle to see the field.
