Jackson doesn't practice

Vikings starting QB Tarvaris Jackson did not practice because of a groin injury today.

Safeties Dwight Smith and Darren Sharper also did not practice, while FB Tony Richardson, RB Chester Taylor and WR Troy Williamson were all limited in practice.

For the Kansas City Chiefs, WR Eddie Kennison has already been ruled out, and OT Damion McIntosh and S Greg Wesley did not practice.

Meanwhile, the Vikings had P Glenn Pakulak at practice today. No, they are not upset with Chris Kluwe, who is among the league leaders right now. They wanted their returners to work with a left-footed punter since they will face one Sunday.
