The anticipated bout between Chris Brown and Soulja Boy will have an added level of intrigue, with Mike Tyson siding with Brown.

The former heavyweight boxing champion announced he will train Brown in a message on his Instagram account Sunday (warning: NSFW language):

The celebrity feud has been growing for weeks, with the two music artists eventually calling to settle things in a fight. Soulja Boy called on Floyd Mayweather Jr. to help train him for the fight and promote it last week.

Mayweather later announced the fight on his own Instagram account, promoted by TMT:

Mayweather retired in 2015 after posting a 49-0 career record. Adding Tyson to the mix makes things more exciting, especially with the 50-year-old willing to use "every dirty trick in the book."

It's hard to imagine the three-round bout resembling Ali-Frazier, but it should at least gain enough publicity to raise some money, perhaps for charity.
