It looks like the Lions will be without their top running back against the Eagles.

After he was declared active to play, reports out of Philadelphia indicate Reggie Bush slipped on the snowy Lincoln Financial Field and aggravated his calf injury.

The Detroit Free Press noticed that Bush was not working with the first-team offense before passing along the news, courtesy of the Lions Radio Network.

If Bush is in fact a no-go, Joique Bell will take the majority of the carries against the Eagles.
