According to Ian Rapoport, Emmanuel Sanders’ foot injury is nothing major.

Sanders left the Lions game in the first half and did not return for the remainder of the game. While the details are not know, the injury is to the same foot that Sanders had surgeries on in 2011. Hopefully, Ian’s source is correct. Mr. Rapoport has drawn heavy criticism for information he received from “sources” recently.
