Less than two months into a breakout season with the Spurs, fourth-year forward Kyle Anderson went down with a left medial knee sprain. Royce Young and Adrian Wojnarowski of ESPN write report that the he underwent an X-ray at the stadium.

The X-ray, a standard procedure in this situation, came back negative but more details as to the severity and timetable of the injury will be brought to light Monday when the 24-year-old undergoes an MRI.

Anderson suffered the non-contact injury in the third quarter of San Antonio’s Sunday night loss to the Thunder.
