Shareef O'Neal just dropped some great news ... telling TMZ Sports Bronny James is doing well following his health scare -- and all signs seem to indicate the medical emergency won't affect his basketball career "at all."
Shaq's son -- who famously battled his own heart problems in 2018 -- provided the positive update while out at LAX on Friday ... saying he's been in contact with his good pal and LeBron James' kid since the 18-year-old returned from the hospital after suffering cardiac arrest.
