LaMarcus Aldridge -- a 7-time NBA All-Star -- just announced he's retiring from the league after learning he played with an "irregular heartbeat."
The 35-year-old Brooklyn Nets star -- who dropped 12 points against the Lakers on Saturday -- made the shocking announcement in an emotional social media post Thursday morning.
"My last game, I played while dealing with an irregular heartbeat. Later on that night, my rhythm got even worse which really worried me even more," Aldridge said.
"The next morning, I told the team what was going on and they were great getting me to the hospital and getting me checked out.
