We'll find out this afternoon who practiced and who didn't. Adam Teicher of the Kansas City Star says LB Cameron Sheffield was nowhere to be found on the field while RT Ryan O'Callaghan was doing conditioning stuff and not participating.
For the Chargers, the big name on the injury report will be LB Shawne Merriman. He participated in individual drills on Wednesday and his status seems to be questionable.
The Chiefs situation with O'Callaghan is quickly becoming a key component of the game. The Chiefs haven't made any roster moves to bring another offensive tackle to the 53-man roster so I would guess they're leaning toward O'Callaghan playing but that's far from confirmed.
Expect to see Sheffield and O'Callaghan on the injury report this afternoon. The Chiefs will also likely list other players who are banged up but participating in practice.
