According to ESPN's Adam Schefter, the NFL can now investigate allegations that Brown intimdated the woman under the personal conduct policy and can do so "without any time pressure." Schefter added "it's hard to imagine another team would attempt to get in the way of that. So Brown's NFL career is on pause and possibly could even be over."
