Oakland Raiders wide receiver Antonio Brown hasn't participated in practice since training camp opened and after looking at his feet, it's pretty clear why.

Brown posted a photo to his Instagram showing his feet and they are ripped up bad and are honestly disgusting to look at.

When Brown is expected to return to camp is unclear and there isn't a timetable at this point but it's clear that some inside the Raiders organization is frustrated.

“I think we're all disappointed,” Gruden said via CBS Sports. “We want to get the party started.”

The Raiders haven't disclosed what injury is keeping him out, but it appears his feet are at least some of the issue. Raiders general manager Mike Mayock pointed out a couple of weeks ago just how important it is for Brown to be at practice because he is a leader.

“I can just tell you that at practice, when he catches a quick slant and gets vertical and goes, it's rare to see grown men in the NFL start looking at each other and start giggling and laughing. And it happens almost every day in practice,” Mayock said. “I think what it also does is the young guys get to see what an All-Pro potential Hall of Famer actually practices on a daily basis. If you're a young guy and you look at that, you'd better understand what it takes.”

Hopefully, Brown's feet heal up quickly so he can get back on the field for the Raiders.
