It was diagnosed during a procedure to clear out an infection in the incision from his heel surgery January 8. He developed an infection from that surgery, and the rupture was diagnosed during a procedure to clean out the infection.
Both that surgery and the next one will be performed by Dr. Robert Anderson in Green Bay, WI.
According to a statement from the Wizards, Wall ruptured his Achilles "after slipping and falling at his home". It was determined it was suffered during a fall at home.
The surgery has still not been scheduled and Wall will not return to full basketball activity until approximately 12 months after the procedure.
It's an ignominious way for Wall, a five-time All-Star and former No. 1-overall draft pick, to lose a year off the prime of his career, but the effect is even more damaging to the Wizards. The Wizards star has had his fair share of injury problems in the past as he only played 41 games last season thanks to a knee injury.
Wall averaged 20.7 points, 8.7 assists and 3.6 rebounds in 32 games this season and will begin a four-year contract extension next season worth $170 million over four years. It increases to a $46.9 million option in the fourth year.
This season, the Wizards are 22-31, level with Orlando for 10th in the Eastern Conference, three games behind Miami for the eighth and final East playoff berth.
