G Brian Waters has a shoulder injury and we're not sure whether he's expected to play or not. If he can't go, Jon Asamoah would take his spot (or Ryan Lilja would and Asamoah would take Lilja's spot). Asamoah played well in relief of Lilja a few weeks ago so this wouldn't be a significant loss for the Chiefs.
S Jon McGraw and S Kendrick Lewis were both listed as questionable. The Chiefs elevated S Ricky Price to the active roster this weekend suggesting one of those safeties may not be able to go. They all traveled to Denver so it will likely be a game-time decision.
WR Dexter McCluster was listed as questionable with an ankle injury although many are not expecting him to play.
The Chiefs injuries this week aren't significant although there's a thought that McCluster's absence is hurting more than we realize.
