For the month of September, there's still no update and we are halfway through the month, it should have one since both camps guaranteed that they will fight this year they need to update this month or later before the month of October so both fighters can concentrate on their training, this has been a long wait so far, and if the fight did not push through, expect a lot of blaming drama on both camps.
I think it's been 4 months already since they started the discussion regarding the undisputed fight last June and yes, we are already half way through the month but still we haven't heard some update from either camps on what is really taking so long. Crawford should start pressuring the opposite camp because he is getting old and he haven't had some fights this year too.
For the blaming season, there's no need for that because the people are already seeing Spence as an obstacle why the fight haven't established until this day and it seems that they aren't ready to risk Spence's record because the current Crawford is not easy to defeat and it will be a real challenge for Spence if he will fight Crawford now.
However, Spence made a big statement last April when he defeated Ugas via TKO because Spence said that he will come for Crawford's belt next. That's why are in this discussion now but unfortunately, the fight might not happen this year.
