Washington Wizards point guard John Wall will reportedly undergo a procedure on his knee that will force him to miss six weeks, Candace Buckner of the Washington Post reported Tuesday. He will also miss the All-Star Game. Buckner called the procedure a "clean up." ESPN's Adrian Wojnarowski confirmed Buckner's report and added that Wall could miss up to two months after undergoing the procedure Wednesday. Wall missed the Wizards' 129-104 win over the Atlanta Hawks on Saturday due to knee soreness, and Buckner reported he was slated to travel to Cleveland to have his knee looked at. The five-time All-Star also missed time in November and December. Wall has a history of knee ailments, as he underwent surgery on both knees during the 2016 offseason.
