It looks like Antonio Brown got cold feet after being traded to the Oakland Raiders.
Brown was placed on the non-football injury list following a mysterious foot injury, but recent reports show that Brown suffered frostbite after using a cryotherapy chamber without the proper footwear. Jon Gruden and the Raiders apparently don't have a timeline for Brown's return to the field, according to reports.
Brown, who was traded to Oakland after a very public fallout with Pittsburgh Steelers head coach Mike Tomlin and quarterback Ben Roethlisberger, hasn't even made it to the first preseason game before he's caused problems in Oakland.
The most noteworthy thing he's done as a member of the Raiders was enter training camp in a hot air balloon.
The Raiders put a lot of responsibility and money into Brown, and he's repaid them by flying around in a balloon and freezing his feet solid.
We can only hope this storyline is alive and well during "Hard Knocks."
