A few Saturday afternoon updates before starting the trek to Detroit:
The Detroit Lions have activated cornerback Drayton Florence from short-term injured reserve and created a roster spot by placing safety Amari Spievey (concussion) on injured reserve. Florence will play Sunday against the Green Bay Packers. Meanwhile, it's fair to question Spievey's future. He's not ready to resume playing a month after suffering a concussion. Last season, a concussion he suffered in the playoffs did not clear until spring practice.
The Chicago Bears have ruled out three players from Monday night's game against the San Francisco 49ers. We already knew about quarterback Jay Cutler and defensive end Shea McClellin, both of whom have concussions. The Bears also won't have defensive tackle Matt Toeaina (toe). Everyone else will be available, including receiver Alshon Jeffery (hand).
Former Bears coach and current ESPN analyst Mike Ditka, who suffered a minor stroke Friday, is hoping to be released from the hospital in time to watch Sunday's games.
