The Oakland Raiders announced Saturday in a tweet that they had released wide receiver Antonio Brown.

"The Raiders have released WR Antonio Brown from the team today," the team's official Twitter account wrote Saturday morning, adding no further detail.

The announcement comes within a day of Brown ramping up his public criticism of the team.

On Friday, Brown published a highly-produced YouTube video that included a recording of a call between himself and head coach Jon Gruden.

On Saturday, Brown posted a graphic on Instagram that read "You are gonna piss a lot of people off when you start doing what's best for you."

The photo's caption read, "I have worked my whole life to prove that the system is blind to see talent like mines. Now that everyone sees it, they want me to conform to that same system that has failed me all those years. 'I'm not mad at anyone. I'm just asking for the freedom to prove them all wrong.' Release me @raiders."
