The Lions sought to upgrade at center this offseason and went out and signed Mays to a three-year, $25 million contract. Now, the 27-year-old lineman is expected to be sidelined for the next 8-10 weeks after , per NFL Network’s Ian Rapoport. Campbell said that the injury is not believed to be season-ending, but it’s still a major blow to the offensive line. Third-year lineman Michael Niese is listed behind Mays on the depth chart and will presumably get the first crack at taking over in his absence.
