Remember Kolby Smith?  The Kansas City Chiefs 5th round draft in 2007?  Well, if you recall, he was injured last year in a game against the Tampa Bay Buccaneers and after the game Herm Edwards announced that he was likely done for the season with a knee injury.

He rehabbed all offseason, usually in what's been dubbed 'No man's land', the area off to the side of the practice field.  He was placed on the Physically Unable to Perform (PUP) list towards the end of the offseason, which means he doesn't count against the 53 man roster for the first six weeks.

When Smith is available to the active roster, I would guess the Chiefs would want to see what he's got, meaning he could hit the practice field for a while.  If that's the case, then someone, very possibly a running back, will need to be released.

I can't imagine a scenario where the Chiefs keep five running backs and cut another position group.  The fourth running back, usually Dantrell Savage or Jackie Battle, has been inactive a few times this season.  Many times, the depth chart doesn't even matter.  Last week, Savage was the third back, Battle the fourth and Savage was inactive.

Battle's big advantage comes on special teams.  Over the offseason, Chiefs coach Todd Haley stressed the importance of special teams, and it appears Battle has taken advantage of that.  Advantage Battle?  Possibly. 

That would leave Savage and Smith battling it out for one spot, if the Chiefs decide to keep only four running backs.

We'll see how things shake out, but I thought this was important to bring up, especially after Battle was promoted above Savage on the depth chart yesterday.
