Kansas City Chies standout safety Eric Berry injured his heel.
He's expected to miss a few days of practice.
Meanwhile, safety Sanders Commings has a fractured fibula and an ankle injury that required surgery Thursday.
Commings got hurt when he was faked out by running back Jamaal Charles.
The Chiefs signed Steve Gregory. Commings is expected to eventually be placed on injured reserve.
