Kawhi Leonard has been battling a sore left knee since early in the Eastern Conference Finals.

Leonard is visibly favoring the knee while running.

Sources tell Sam Amick and Joe Vardon of The Athletic that Leonard's knee issue comes from overcompensating for his injured right quad. Leonard missed nearly the entire 17-18 season with the San Antonio Spurs due to the quad injury.

The right quad, however, is fine currently. 

“I don’t think the leg trouble is much of an issue,” said Nick Nurse after Toronto's Game 2 loss to the Warriors.
