The Kansas City Chiefs filed their first injury report with the league office listing two players for the Thursday edition.
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.
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.
