Jermell Charlo is unsure if his twin brother Jermall Charlo will even attend his fight with Canelo Alvarez on Saturday night.
The 33-year-old American world champions have been ever-presents by each other's sides for the majority of their careers.
However, in recent months their relationship has deteriorated.
WBC middleweight (160lbs) world champion Jermall has been out of the ring for over two years as he battles with personal issues and mental health concerns.
During this time, he has clashed with his brother and their wives have even been seen fighting in public, though many of the specific details of the rift understandably remain private.
Meanwhile undisputed WBA, WBC, IBF and WBO super-welterweight (154lbs) world champion Jermell is now set for the biggest fight of his career.
