FOXBOROUGH, Mass. — Antonio Brown was released by the New England Patriots on Friday after a second woman accused him of sexual misconduct — the third team in seven months to tire of the off-field behavior that has overshadowed his accomplishments as one of the NFL’s most prolific receivers for a decade.

The defending Super Bowl champions announced the move in a statement emailed to reporters, three minutes after Brown posted on Twitter about his release.

Already facing a civil suit claiming that he raped a former trainer, Brown was accused in a Sports Illustrated story published on Monday of exposing himself to an artist he hired to paint a mural at his home. He has denied both allegations.

But the Patriots cut ties with the four-time All-Pro after just one game.

An NFL investigation of the allegations against Brown is ongoing. The league said in a statement late Friday that Brown could be placed on the commissioner’s exempt list.
