Sidelined for 'extended period'
Mays sustained a wrist injury during Sunday's practice and will miss "a significant period," Dave Birkett of the Detroit Free Press reports.
It's unclear exactly how long Mays will be sidelined, but his recovery timeline will extend into the regular season. As such, the Lions will be down their top center -- who signed a three-year, $25 million contract with the club in March -- when the games that count get underway.
