Antonio Brown practiced with the Oakland Raiders on Tuesday while wearing a certified helmet, Jon Gruden said.
"He's all-in and ready to go," Gruden said. "That's my understanding. Really happy to have him out here. He's a great player."
The coach told reporters that there's been "no distractions" for him or the team concerning Brown, whose second grievance hearing with the NFL will be presided by the same arbitrator from his first hearing and is scheduled for Friday morning, according to a source.
