Wizards guard John Wall underwent an MRI exam yesterday after experiencing left knee discomfort and inflammation due to knee-to-knee contact in the team’s game on Nov. 7 vs. Dallas. Following consultation with Dr. Richard D. Parker at the Cleveland Clinic Marymount and Wizards Head Team Physician Wiemi Douoguih, Wall will receive PRP (platelet-rich plasma) and viscosupplementation injections to reduce the inflammation in his left knee.
