Baltimore will open training camp practices without its first-round wideout available.
The Oklahoma product suffered the foot injury during the Sooners' win over Texas in the Big 12 Championship in December and did not participate in combine drills in February. Still, Baltimore made him the first receiver taken in the draft.
As for his timetable to return, Brown is progressing well and expected to be back on the practice field in a few weeks, NFL Network Insider Ian Rapoport reported Thursday.
Brown and the rest of his teammates can be taken off the NFI list, which is reserved for players unable to practice for reasons unrelated to professional football, once medically cleared.
