Cardinals' John Brown: Sickle-cell trait still a concern

Per coach Bruce Arians, there's still a little concern about the potential for Brown's sickle-cell trait to be a problem moving forward, ESPN's Josh Weinfuss reports.

Brown's condition, which was diagnosed in Week 7 of last season, is concerning because people with the sickle-cell trait are more likely to experience muscle breakdown when doing intense exercise, according to Weinfuss. While Brown only missed one game, he was clearly hampered in plenty of others and ultimately finished the year with career lows in nearly every receiving category. In February, a member of the Cardinals' brass suggested the team may have found a solution to Brown's issue. While they indeed may have discovered a way to keep it under control, Sunday's report reminds prospective fantasy owners that this sickle-cell trait could resurface at any point in the future.
