The whole reason why John Wall has been sitting out is to avoid further injury to his nagging heel injury, which had been bothering him earlier in the season and forced him to undergo surgery.

You would think Wall would have been safe within the comfort of his own home, but unfortunately, that wasn't the case.

The Washington Wizards point guard tore his Achilles after slipping and falling at home on Tuesday, knocking him out of action for a long, long time.

According to Candace Buckner of The Washington Post, the long end of a full recovery for Wall will be 15 months.

Wall, who had been wearing a boot, tore his Achilles with the boot off. His doctor says it likely occurred when the 28-year-old took his boot off to take a shower.

Remember: Wall signed a massive four-year, $170 million contract extension with the Wizards last summer, and next season was set to be Wall's first year of that deal.

Wall played in 32 games during the 2018-19 campaign, averaging 20.7 points, 8.7 assists, 3.6 rebounds and 1.5 steals over 34.5 minutes per game while shooting 44.4 percent from the floor, 30.2 percent from 3-point range and 69.7 percent from the free-throw line.

The Raleigh, N.C. native, who played his collegiate basketball at the University of Kentucky, was originally selected by Washington with the first overall pick of the 2010 NBA Draft.

Wall made his first All-Star team during his fourth season and then proceeded to make five straight All-Star appearances, with his best season coming in 2016-17 when he registered 23.1 points and 10.7 assists per game.
