Last week, the Chiefs were without starting right tackle Ryan O'Callaghan. He hasn't practiced since then so we can probably expect to see him on the sidelines Thursday. We're not sure what O'Callaghan's injury is or if it's serious.
The Chiefs may also be missing starting outside linebacker Tamba Hali. The Kansas City Star reports Hali had his "ankle heavily taped" while working out on Tuesday. Again, there's no specifics on his injury.
Chiefs coach Todd Haley has previously said that generally players need to practice to play. I imagine he'd be willing to break that rule in the regular season when the games count. In the preseason, though, there's no reason to push players who are hurting.
Also missing practice this week has been the usual suspects: Guard Darryl Harris, outside linebacker Cameron Sheffield and defensive back Maurice Leggett. We're not sure if any of those guys will play but it seems unlikely.
Chris Chambers also missed practice but Haley indicated that "we're in good shape" when asked about him.
