An MRI on Tuesday confirmed the Lonzo Ball has a low-grade calf strain in his right leg.
Ball — who suffered the injury during Sunday’s Summer League semifinals against Dallas — does not have an official timetable to return, but does plan to rest for one or two weeks.
The 19-year-old did not play in the Las Vegas Summer League championship game, but was named the event’s Most Valuable Player after averaging 16.3 points, 7.7 rebounds, 9.3 assists and 2.5 steals.
His assists were the most in Summer League history, and his two triple-doubles were the first in Vegas in a decade.
Despite missing Ball, the Lakers defeated Portland for the Summer League title behind 30 points and 10 rebounds from championship game MVP Kyle Kuzma.
