Shareef O'Neal will miss the entire 2018-19 season for UCLA after doctors discovered a heart ailment that will require surgery.

O'Neal is a four-star recruit.

"So, the other day during routine checkup, we found a medical issue dealing with my heart," O'Neal said in the video. "And thank God UCLA medical staff found it early, but causing this I will not be playing this season and I will be a medical redshirt. But during this time off, I'll be off for a while, I'll be focusing on academics, my health, of course, and I'll just be observing to be the best player I can be next year."

In the TMZ Sports video, O'Neal stressed that he will return.

"I know it's an injury that requires surgery, so I'll be having heart surgery and I'll be out a couple months and after that I'll be back," he said in the video. "A lot of people are asking if it's career-ending. The answer is absolutely not. Just a little bump in the road. ... During my rehab, I'll be attending my classes and being a normal student. But that's what's going on, and I'd like to thank UCLA, my family, my teammates and everyone who supports me in this decision."

Wayde Sims was killed in a shooting early Friday morning near the campus of Southern University.

Sims was entering his junior season at LSU.

Sims averaged 5.6 points and 2.6 rebounds per game this past season with 10 starts in 32 games.

Wayde Sims' father, Wayne, also played forward on the LSU basketball team coach Dale Brown from 1987-91.
