Anthony Rendon was scheduled to meet with Dr. Steven Singleton in Vail, Colorado, for a third opinion on his injured left knee.
Dr. James Andrews on Monday confirmed the Washington Nationals' initial diagnosis of a sprained medial collateral ligament.
"We're just trying to make sure we cover all bases and everybody gets a chance to take a look at it and develop a course of action from today on," Matt Williams said.
Rendon was hurt making a diving stop in a game against Atlanta on March 9.
