Antonio Brown needs to be ‘all in or all out,' Raiders GM Mike Mayock says

Jon Gruden thinks Antonio Brown will be practicing with Raiders soon

Antonio Brown was not with the Raiders on Sunday.

The 31-year-old wide receiver skipped practice because he continues to be unhappy about his ongoing dispute with the NFL over his helmet, Oakland general manager Mike Mayock revealed when he met with reporters.

“Here’s the bottom line,” Mayock said. “He’s upset about the helmet issue. We have supported that, we appreciate that. At this point, we’ve pretty much exhausted all avenues of relief. So, from our perspective it’s time for him to be all in, or all out. We’re hoping he’s back soon.

“We’ve got 89 guys busting their tails. We’re really excited about where this franchise is going and we hope A.B. is going to be a big part of it, starting Week 1 against Denver. End of story.”

Mayock declined to take questions from the media Sunday. 

Brown has also dealt with frostbitten feet, an injury caused by a cryotherapy equipment mishap, in training camp.
