LaMarcus Aldridge took the NBA world by storm with his shocking retirement announcement on Friday morning. His former coach from the San Antonio Spurs, Gregg Popovich, has caught wind of this truly unexpected development and has since come out with his own statement addressing Aldridge's sudden retirement.

This comes via Tim Reynolds of the Associated Press:

Aldridge announced his decision to call it a career in the wake of a heart problem he has been dealing with. The veteran has been diagnosed with an irregular heartbeat and it has been determined that his best course of action would be to retire from professional basketball.

Aldridge spent six years in San Antonio playing under the great Gregg Popovich. After a lengthy spell with the Spurs, both parties agreed on a buyout agreement late last month which allowed Aldridge to sign with the Brooklyn Nets as a free agent.

LMA played some of the best basketball of his career with the Spurs. He was named an All-Star twice while in San Antonio, and he served as a key cog for the squad for many years.

It is clear that Popovich, the Spurs organization, and the city of San Antonio hold Aldridge in high regard. As coach Pop said in his message above, the Spurs truly appreciate all the hard work and sacrifice Aldridge put in during his time with the Spurs. It was truly a memorable run, and LMA will forever be a part of San Antonio's rich history.
