Report: Brown day-to-day after seeing foot specialist

Oakland Raiders wide receiver Antonio Brown is considered day-to-day after visiting a foot specialist, a source told Ian Rapoport of NFL Network.

Brown has missed a significant portion of his first training camp with the Raiders. He began camp on the non-football injury list with an undisclosed injury, which was later reported to be sore feet.

After Tuesday's practice, Brown posted a picture on Instagram of his feet covered in blisters but later deleted the post.

Head coach Jon Gruden said Friday the team is frustrated its top weapon hasn't been able to get onto the field.

"I think we're all disappointed," Gruden said, per ESPN's Paul Guiterrez. "We think he's disappointed. We'd like to get the party started. We'd like to get him out here. He's a big part of the team.

"I want the guy out here as soon as possible. I'd like him to never leave and stay in the huddle every play. But life goes on and you've got to continue to work, and the other guys got to take advantage of these opportunities, and so far, they have."

Brown was cleared July 28 but has yet to fully participate in practice.
