Reigning Defensive Player of the Year, Marc Gasol went down last night after a knee injury. As the Grizzlies took on the Spurs Friday night, Gasol left early in the second quarter after what appeared to be a sprain in his left knee. After undergoing an MRI on Saturday, it was determined that Gasol has a Grade 2 sprain his left medical collateral ligament (MCL). While no surgery is required, there’s no timetable set for his return.
