Daniel Jacobs threw out a challenge on Twitter, and Billy Joe Saunders answered. It's still just Twitter, but hey, boxing doesn't produce that much to talk about, so enjoy this sorta-story!

@DanielJacobsTKO you want me I'll kick your ass son ' your not even world champ belt number2 you hold — billyjoesaunders (@bjsaunders_) March 28, 2016

Jacobs (31-1, 28 KO) is the WBA "world" titleholder at middleweight, possessing a secondary version of one of the belts that Gennady Golovkin holds, while Saunders (23-0, 12 KO) holds the WBO title right now.

Saunders was offered a fight with Golovkin a little while back, but turned it down, which was frankly understandable and hardly an outstanding "duck" in the boxing business. Saunders won the WBO title from Andy Lee in December, and will face Max Bursak (32-4-1, 15 KO) on April 30, in what amounts to a "stay busy" fight for a first world title defense.

Jacobs is coming off of a big, impressive win over Peter Quillin, also in December, where he stopped the former titleholder in the first round. He currently has nothing scheduled.
