Brandon Browner is now being accused of much more than attempted murder of his ex-girlfriend -- 'cause she's suing him, and claiming multiple instances of domestic violence.
The former Seattle Seahawks star was just sued by his ex for multiple alleged attacks that she says occurred between 2016 and 2018 -- including the attempted murder case last year, for which he was convicted and is currently serving 8 years in prison.
In the docs, obtained by TMZ, the woman says she'd suffered numerous acts of violence at the hands of Browner dating back to July 2016, when she says they were still a couple.
