Okafor was forced out of Monday's game versus the Bills with a hamstring injury.
Okafor dealt with a hamstring injury earlier this season that kept him out of two September games, and it's unclear if this is related. It's difficult to return to games after leaving with a soft-tissue injury, so it wouldn't be surprising if Okafor is done for the evening. Taco Charlton should see additional snaps in place of Okafor.
