The Vikings are preparing for their regular season opener Sunday at Detroit at noon, pregame on WJON at 11am.  Defensive tackle Kevin Williams is questionable to play due to an injury at San Francisco in the Vikings 3rd preseason game.  Williams has a hyper-extended knee and could miss the game.  How much he practices this week could be a strong indication.

Rookie Defensive tackle Sharif Floyd could see more time Sunday against Detroit if Williams is unable to go.  Floyd is expected to play regardless after suffering an injury of his own earlier in the preseason.

Detroit is favored by 1 1/2 points against the Vikings Sunday.
