The Jacksonville Jaguars are thrilled with the play of Gardner Minshew II, but they are worried about the quarterback taking low hits.

Minshew has been wearing a knee brace since taking several hits against the Denver Broncos.

"I would hope that everyone's doing what they're supposed to do and those are penalties for hitting him low," Doug Marrone said. "I think you get concerned when things are happening to your team that aren't getting called. ...

"Obviously, those things … We have the ability to turn them in, make people aware of it prior to [a game]. But ... during the course of the game, you like to see that stuff get called and make sure that player safety is the number one thing that we harp on and we talk about. So, that's the one thing that we should be doing well."
