Coach Scott Brooks said Wall was getting an MRI on Monday and then heading to the Cleveland Clinic to meet with orthopedic surgeon Richard D. Parker, who performed two knee surgeries on Wall in May 2016 and consulted with Wall when he started experiencing inflammation and soreness in November.
"It's just [that] it's sore. We have to figure out why is it doing that every so often," Brooks told reporters, according to the Washington Post. "It's really just in the short term we're concerned because it's sore, but other than that, we feel comfortable with him being able to go forward, but we definitely have to do what's best and go from there."
Wall's knee required an MRI earlier this season and has also been drained and received injections. As for the visit with Dr. Parker, Brooks said, "We just know that they're going to all meet, and we're going to go from there ... The next couple of days we'll know more."
Wall, who is slated to play for Team LeBron on Feb. 18 in Los Angeles in what would be his fifth straight All-Star Game, is averaging 19.4 points and 9.3 assists this season, both numbers a little better than his career averages.
