The Lions will not throw new defensive end Lawrence Jackson into the fire. He is one of four Lions who officially won’t play on Saturday night in Denver. Others who will sit out will be announced Saturday, possibly at game time.

Also out will be defensive end Jared DeVries, who hasn’t practice for weeks with a leg injury; cornerback Aaron Berry (thigh) who also hasn’t practiced and cornerback Jack Williams who is coming off ACL surgery and still on the physically unable to perform list.

Also on Friday, the Lions waived OL Roy Schuening (injured) and signed T Noah Franklin, a rookie from Oklahoma State who had been waived by the Carolina Panthers on Aug. 8.
