Earlier this week, it was reported that Antonio Brown had suffered frostbite on his feet after using a cryotherapy machine, which has caused him to miss every single practice so far for training camp.
According to four sources familiar with Brown's current absence from camp, which dates back to late last week, Raiders coaches and players are concerned that the receiver's unhappiness regarding the helmet issue might be playing a role in his decision to stay away from Napa.
The Raiders have been sending Brown other approved helmets to wear, but at this time, he is not interested in wearing any of them.
According to Schefter, the stance stems from the National Football League blocking the use of the helmet Brown has worn throughout his career. It had seemed that the Raiders were mum in order to avoid making Brown look bad or foolish for freezing his feet; maybe the Raiders are saying nothing because there's nothing to say, and because they just don't know what's going on. Brown's helmet can not be recertified because it is more than 10 years old.

Mr Donohoe said the appointment of Mr Johnson as Prime Minister had "added a new dynamic" to Brexit talks. Trade Secretary Liz Truss is in Washington to meet figures including secretary of commerce Wilbur Ross.
Now, Schefter is reporting Brown is SO upset over not being able to use his favorite headgear - he's threatening to RETIRE if he doesn't get his way!
The post led to plenty of speculation about what happened to Brown's feet.
