Denver Nuggets point guard Nate Robinson has sustained a sprained ACL, with no timetable on his return.
Robinson was promoted to a starter in the absence of the injured Ty Lawson, but has suffered a blow with his injury setback.
The 29-year-old is averaging 10.4 points and 2.5 assists per game this season following his move from the Chicago Bulls.
Lawson is listed as day-to-day with a rotator cuff injury, while Randy Foye and Evan Fournier will now be expected to fill in.
