Its bullshiit. The artical doesnt say his career is over, it says the doctor wont be happy until he sees 3 months of clear no symptoms from Dirrell. Doesnt that tie in well with having the others fight and then coming back in to it?

I think a proper round robin or league would be a good idea. Get, say, at least 4 of the top in the weight and have them fight each other every 3 or 4 months and get the fights on the same night and show, run it over a year. It would be massive, plenty of recovery time and deffinitly get to see the top in the division.
