According to Chris Hayne of cleveland.com, Williams' left knee is still bothering him and he'll remain in Cleveland to receive further treatment. According to Haynes, Williams visited Dr. James Andrews in Florida on Tuesday and was diagnosed with chondromalacia, which the Mayo Clinic says is also known as runner's knee. It is typically caused by overuse. It results in a dull pain in front the knee.
This leaves the Cavs with just Kyrie Irving and Matthew Dellavedova for the next two games, but that shouldn't be much of an issue. Williams, after playing consistent minutes and starting a few games at the beginning of the year, hasn't played much of late. At this point, he's insurance for potential injuries to Irving and/or Dellavedova.
For the year, Williams is averaging 8.9 points and 2.7 assists in 35 games. Williams' status will be evaluated after the Cavs' game Friday in Toronto and Sunday in Washington.
