The scope is designed to remove a loose body in his knee, sources said.
Morant, 19, is the Memphis Grizzlies' target with the second pick in June's draft, sources said. Morant's agent, Jim Tanner of Tandem Sports, informed teams at the top of the draft -- including New Orleans, Memphis and New York -- of the impending procedure on Saturday, sources said.
Along with Duke forwards Zion Williamson and RJ Barrett, Morant is one of the dynamic talents on the cusp of entering the league. Morant averaged 24.5 points and an NCAA-leading 10 assists in his sophomore season.
