The Kansas City Chiefs filed their first injury report with the league office listing two players for the Thursday edition.
LB Cameron Sheffield did not participate in practice with a neck injury and RT Ryan O'Callaghan was limited in practice with a groin injury.
We never knew what O'Callaghan's injury was. A groin's one of those injuries that can be aggravated if you don't take your time.
The San Diego Chargers also listed a pair of players on the injury report.
QB Billy Volek did not participate in practice with a knee injury and LB Shawne Merriman was limited in practice with an Achilles' injury.
We'll see another injury report like this for Friday. On Saturday, we'll see the final injury report with designations of probable, questionable doubtful and out.
