NEW YORK  — Brooklyn Nets center and seven-time All-Star LaMarcus Aldridge Thursday abruptly announced he’s ending his NBA career after experiencing an irregular heartbeat during a Saturday victory over the Los Angeles Lakers.

Aldridge, 35, made the announcement on social media, calling the medical episode one of the “scariest things” he’s ever experienced.

“I’ve made the difficult decision to retire from the NBA. For 15 years, I’ve put basketball first, and now, it is time to put my health and family first,” he wrote.

Aldridge signed with the Nets on March 28 and he had become their starting center. He missed the last two games with what the team had called a non-COVID-19 illness.

“I’m thankful for everything this game has given me: the great memories, including all the ups and downs, and the friendships I’ve made and will keep with me forever,” Aldridge continued. “I thank Portland for drafting a skinny, Texas kid and giving him a chance. The city of Portland has given me some unforgettable years. They will always remain in my heart.”

After spending nine seasons with the Portland Trailblazers, Aldridge signed with the San Antonio Spurs in 2015.

“I want to thank the Spurs for letting me into the family and giving me 5 fun years. Last but not least, I want to thank Brooklyn. You wanted me for me,” he wrote. “In a game that’s changing so much, you asked me to come and just do what I do which was good to hear.”

Born in Dallas, Aldridge declared for the NBA draft in 2004 but ultimately withdrew his name, opting instead for the University of Texas at Austin. He played at Texas until 2006 when he left the Longhorns in order to enter the 2006 NBA draft.

Known for his fadeaway jump shot, Aldridge was selected to five All-NBA teams.
