"The April 8th, 2019 purse bid for the WBO Light heavyweight bout between Champion Sergey Kovalev and mandatory challenger Anthony Yarde has been postponed for another week by request of Kovalev's promoter, Kathy Duva. More details to come." It could be a good sign. Maybe they're trying to come to an agreement without a purse bid.
Looks promising. Pretty sure it won't happen if it really goes to pursebids, because either team Yarde pulls out if they don't win the bid, and if they do they have to pay Kova 4 times what "a-side" Yarde gets, which won't happen either.
