Cedric Ceballos, a former 11-year NBA veteran, sent several tweets on Monday detailing his battle with COVID-19. He has since been removed from isolation, but he remains in the intensive care unit despite being COVID-19 free. 

Ceballos said he is still dealing with several lingering effects related to the virus. 

In one tweet, Ceballos went on to thank supporters who are wishing him well, but he explains that is still unable to “breathe, walk or function” on his own. 

“I will still fight and I ask for uplifting on your end,” Ceballos said. 

Ceballos, 52, tweeted a photo of himself while he was at the hospital. In the photo, he is wearing an oxygen mask and was fearful of his health at the time as he asked for prayers and wanted to publicly apologize to anyone he had wronged. 

According to the Centers for Disease Control and Prevention, although most people with COVID-19 get better within the weeks following recovery from the illness, some people experience post-COVID conditions.

A recent CDC study shows that adults who had COVID-19 may experience ongoing health problems that can last four or more weeks after COVID-19 infection. Health problems may include shortness of breath, fatigue, difficulty concentrating (“brain-fog”), headache, fast-beating or pounding heart, cough, joint or muscle pain, dizziness/lightheadedness, or mood changes, among other symptoms. 

Even people who did not have significant COVID-19 symptoms in the days or weeks after they were infected can have post-COVID conditions. 

In Ceballos’ 11 years in the NBA, he averaged 14.3 points per game. He played with the Phoenix Suns (twice), Los Angeles Lakers, Dallas Mavericks, Detroit Pistons and Miami Heat. He made the All-Star Game with the Lakers.
