For the Oakland Raiders, having everyone on deck is necessary with NFL training camp underway. And while it has only been over a week, a notable missing figure in the mix is Antonio Brown. The 31-year-old wide receiver is reportedly having issues with his right foot and multiple reports single out how it was in pretty bad shape.

Brown showed on his Instagram a pair of blistered feet which have been singled out as the reason why he has been kept off the field. And while the injury was not initially seen as something that would keep him out of practice as the Raiders prepare for the coming NFL season, it appears that the $50 million pass-catcher continue to have issues with his fickled foot, NFL.com reported.

It hardly surprises many that coach Jon Gruden was a bit disappointed at the status of Brown. In an interview with ESPN, he stressed how important the wide receiver was to the team. In the meantime, he will have to make do with other receivers they feel have potential.

A prime reason why the Raiders want Brown on the field is that they want him to develop chemistry with quarterback Derek Carr and the rest of the offense. But with the 31-year-old saying that his right foot was bothering him more than his left, it all depends on the advice given by the foot specialist. In short, he could suddenly return to the field without anyone even expecting it.

The good news is that Brown looked good in one short practice. He was beating cornerbacks for touchdowns in one-on-one drills although may need more than that to prove he is ready for the coming NFL season. His chemistry with Carr is one thing that most are concerned off although both have already used the entire summer working on that.

The Raiders acquired Brown from the Pittsburgh Steelers in the offseason and will undoubtedly be one of the NFL Hall of Famers looking ahead. He has recorded at least 100 receptions in each of the last six seasons. Brown is also the only player in league history to accomplish that feat, and his six seasons of 100-plus grabs are tied for the most in NFL history.

With so much going for him, the most important thing right now for Gruden and the Raiders is having Brown on the field. Unfortunately, that is an answer that only the 31-year-old wide receiver can answer.
