Sabrina Ionescu exited the New York Liberty's 79-67 preseason win against the Connecticut Sun on Sunday after she landed awkwardly during a drive to the basket in the third quarter.
The All-Star guard stayed down for a few seconds before getting up, waving toward New York's bench on the other side of the court and walking with a slight limp back to the locker room. She was ruled out for the remainder of the game with what the team called a lower-body injury.
Liberty coach Chris DeMarco said after the win that Ionescu had rolled her left ankle and will have an MRI on Monday.
"[Things are] positive right now," he said. "We're just gonna do the test tomorrow and that's the only update I have."
Ionescu had six points in just under 16 minutes of play. She was 2-for-8 from the field.
"Obviously, it wasn't good to see," Liberty center Jonquel Jones said. "Like Chris said, our fingers are crossed and we'll just kind of handle it as we get more information."
The Liberty open the regular season at home Friday against Connecticut.
Ionescu played in 38 games last season for New York, averaging 18.2 points, 5.7 assists and 4.9 rebounds.
The Liberty played Sunday without Betnijah Laney-Hamilton, Rebecca Allen and Satou Sabally, all of whom were working their way back into shape.
