The Kansas City Chiefs listed four players as out on the Wednesday injury report.  Today, it looks like at least one of those players will be upgraded.

LB David Herron, who was out all of last week, returned from a knee injury to at least partially participate in practice.

Josh Looney of KCChiefs.com also reports that CB Travis Daniels has been seeing time at nickelback over CB Mike Richardson.  This could mean Daniels gets more time on Sunday.

Other Chiefs missing practice include:

LB Mike Vrabel - He's still recovering from a knee injury suffered in last Sunday's win over the Raiders.  He came out in the middle of the third quarter and did not return.

Andy Studebaker took first team reps in his place.

G/C Andy Alleman - No word yet on what Alleman's injury is but he was out yesterday as well.  Wade Smith has been taking reps in his place.  With G Mike Goff headed to injured reserve last week, this is becoming a thin position.

RB Dantrell Savage - He's got an ankle problem and it doesn't bode well if FB Tim Castille was signed and the head coach referenced Savage's injury as a reason for Castille's signing.

As of now it doesn't look good for Savage on Sunday but we'll take a wait and see approach.
