Kraemer (back) was placed on injured reserve Thursday.
Kraemer missed Week 1 with the injury, and he'll now miss at least the next four weeks with his move to IR. With Halapoulivaati Vaitai also nursing a back injury, the Lions' depth at right guard has taken a hit to begin the season. Logan Stenberg will likely draw the start at the position once again in Week 2, and Detroit also signed Kayode Awosika from the Eagles' practice squad to add depth on the offensive line.
