"Solid talent, versatile. ?? marks around team culture + habit of endless self promotion. Doctors will need to do medical as body has been banged up."
Many on social media found the remarks to be offensive ... as they were clear digs at Jenner's past relationships with multiple NBA stars.
After nearly four days of hearing the criticism, Bogut didn't walk back the remarks ... and instead, the ex-Milwaukee Bucks center pressed further with the trolling.
"I would like to formally apologize for this tweet," he said. "My scout take forgot to include the elite level of rebounding. I will do better in the future."
Jenner is no stranger to the heckling ... she's, in the past, actually addressed fans who have taken shots at her over dating NBA players, saying on an episode of "Keeping Up With The Kardashians," "I'm not ashamed that I have a type, and I'm also a genuine basketball fan."
FYI, it's still unclear if Jenner and Booker are even broken up -- the two were spotted looking flirty at Soho House in Malibu on Sunday.
