I thought an operation was required. Thank you for correcting me.
40% of the re-match purse still will many millions of USD$ but will it be enough to entice Wilder to trigger the re-match? He has well over 3 weeks to make up his mind, I am sure Wilder and his team will go over everything. Even if he triggers the clause for the re-match he might not be able to fight in the stipluated time-frame because it will take time after the operation on his ear to heal.
What operation? Source? Apparently he just needed some stitches which will be long-healed by the time a rematch happens which will be in the summer if it goes ahead.
