The Chiefs placed Okafor (hamstring) on injured reserve Saturday.
Okafor suffered a hamstring injury during this past Monday's win over the Bills, and apparently it was serious enough to keep him out for the next three games. It's possible this injury is related to the one that kept him out Weeks 2 and 3. Nevertheless, Okafor will aim to return Week 11 against the Raiders, and Demone Harris figures to handle an expanded role behind starter Tanoh Kpassagnon.
