DETROIT -- Kerron Johnson's injury appears to be minor, but concern is growing for Jamal Agnew.
The Detroit Lions' All-Pro punt returner suffered a knee injury in the second half of a 31-23 win Sunday against Green Bay. He writhed in pain on the field, then was eventually helped to the sideline before being carted to the locker room.
Detroit does have a bye next week, which gives Agnew extra time to rest. But the injury could be serious enough that an extra week won't matter.
"We'll find out when we get that evaluated," coach Matt Patricia said after the game.
