“To all the people who are worried and concerned, first off, let me say thank you. And lastly, no need to worry just had to get some BBL WORK AKA #hipreplacement,” he wrote in another tweet. “Thanks and love you all, but no need to worry, and, yes, I’m fine.”

ET reported that the former NBA great underwent hip replacement surgery on March 15.

The entertainment publication also reported that O’Neal, who turned 51 on March 6, recently opened up about prioritizing his health. In December, he said he’d lost 40 pounds and planned to lose 20 more after the results of some blood work prompted him to get a checkup and improve his diet, ET reported.
