Cleanliness is the watchword in Kansas City.

Players are being told to wash their hands thoroughly with soap and hot water to keep anyone from getting sick. Pro Bowl left guard Brian Waters missed a second straight practice Thursday as the Chiefs prepared to host Baltimore on Sunday in the first round of the AFC playoffs.

Pro Bowl wide receiver Dwayne Bowe was back after being out sick on Wednesday.

As another precaution, players are removing their practice jerseys and putting them in a big hamper before they go into the locker room.

Said coach Todd Haley: "We've had a re-emphasis lesson, kindergarten rules, wash your hands in warm water, two minutes. As always, we know we're doing a good job in our building, trying the best we can to keep the germs out. Then you go home and it all gets thrown out the window in my case."
