VIDEO: Jon Gruden Roasts Antonio Brown With Foot Joke During Latest 'Hard Knocks' Episode

The Oakland Raiders are the focus of the 2019 edition of HBO's "Hard Knocks" and during a scene at the team's practice, Jon Gruden trolled his star receiver Antonio Brown. Brown was complaining about his feet hurting and being too hot, when Gruden sarcastically suggested the 30-year-old go for cryotherapy treatment.

In case you were unaware amid all of the recent helmet drama, Brown recently suffered serious frostbite on his feet after an incident in a cryotherapy chamber. Gruden didn't seem to think the subject was a sensitive one and hilariously ripped into Brown during practice.

Brown's response of "f*** that" was probably the right one, as we doubt the wideout will ever step foot in a cryotherapy chamber again after that terrifying experience.
