It was later revealed that Rondo suffered an orbital fracture in his left eye and a nasal fracture.
Dallas acquired Rondo in a December trade with the Boston Celtics. Over 21 games with the Mavericks, the 28-year-old has averaged 9.2 points and 6.5 assists while shooting 40.4 percent from the field.
The Mavericks improved to 34-18, good for sixth place in the Western Conference, by winning in Sacramento on Thursday. Dallas will face the Portland Trail Blazers on Saturday.
