The Chiefs started the three-week clock on running back Kolby Smith, who participated in practice today. The Chiefs now have three weeks in which to elevate Smith to the active roster. If they fail to do so in that timeframe, he can't practice or play the rest of the season.

But look for the Chiefs to eventually activate Smith. The Chiefs have to figure out a role for Smith, but he may be able to help their ailing running game in some manner.
