LaMarcus Aldridge, a seven-time All-Star who scored over 20,000 points over an accomplished 16-year NBA career, officially announced his retirement on Friday.

Aldridge has not played this season after appearing in 47 games with the Brooklyn Nets in 2021-22.

The 37-year-old briefly retired following the 2020-21 season after being diagnosed with an irregular heartbeat but returned to the Nets the following September after receiving medical clearance.

And Aldridge channelled one of the great sports stars in his announcement.

"In the words of [Tom Brady], you only get one big, emotional retirement," Aldridge wrote on his Twitter account.

"So, on that note... I'm thankful for all the memories, family and friends I made throughout my career. It was one hell of a ride and I enjoyed every min!"

Aldridge entered the NBA in 2006 as the second overall pick of that year's draft following a standout career at the University of Texas.

He spent his first nine seasons with the Portland Trail Blazers and is the franchise's career leader in rebounds, while his 12,562 points in a Blazers uniform trail only Damian Lillard and Hall of Famer Clyde Drexler.

The power forward made four All-Star teams in Portland and was an All-NBA second team selection in his final season with the Blazers in 2014-15 after averaging a career-high 23.4 points per game.

Aldridge left Portland following that season to return to his native Texans by signing a four-year, $80million contract with the San Antonio Spurs. He earned three more All-Star selections over six seasons with San Antonio and again garnered second team All-NBA honours in 2017-18.

The Spurs bought out Aldridge's contract in March 2021 and he signed with the Nets just days afterward in hopes of winning a first NBA championship, though he played just five games over the remainder of that season due to a rapid heartbeat that led to his temporary retirement.

Aldridge became the 48th player in NBA history to reach 20,000 points during his final season and finished his career with 20,558 points, good for 46th place on the NBA's all-time scoring list.

He is one of only 16 players in league history to record 20,000 points and 1,000 blocked shots in a career.
