Wall is averaging 19.4 points in 37 games and ranks second in the National Basketball Association in assists per game (9.3).
The Washington Wizards are set to enter a critical stretch of the National Basketball Association season, but they'll need to survive the important period without All-Star guard John Wall. (He was voted in as a starter in 2015.) In his absence, the National Basketball Association, which decides all injury replacement matters, will likely elevate either Ben Simmons or Kemba Walker into his spot. Two months will spit Wall back onto the court at the end of March, with roughly 20 games remaining for another Washington playoff push. He was voted into the game as a reserve along with teammate Bradley Beal last week, giving Washington its first pair of all-stars in the same season in 10 years. The Wizards are 6-6 in those games. The Wizards enter Tuesday at 27-22, good for sixth in the Eastern Conference.
