Jahvid Best will play, but at what level?

GREEN BAY, Wis. -- The Detroit Lions will have tailback Jahvid Best for Sunday's game against the Green Bay Packers. It will be interesting to see how long Best can go, and how effective he will be, after the injury forced him out of last weekend's game against the Minnesota Vikings and required two days off from practice during the week.

For insurance, the Lions have activated Kevin Smith for the first time this season. But they still only have three tailbacks available because of Aaron Brown's fractured hand.

As expected, the Lions will be without receiver Nate Burleson and linebacker DeAndre Levy. Landon Johnson will start at middle linebacker for Levy, who has now missed three of the Lions' first games.

Meanwhile, the Packers had no surprises on their deactivation list. Nickelback Sam Shields and linebacker Brandon Chillar are both inactive. Brandon Underwood and A.J. Hawk likely will be their fill-ins Sunday.
