Sabrina Ionescu was set to have an MRI on Monday after injuring her left ankle Sunday in the New York Liberty's 79-67 preseason win over the host Connecticut Sun.
The Liberty said they are hopeful it's nothing major. The regular season starts Friday night with New York hosting Connecticut.
"[Things are] positive right now," first-year Liberty coach Chris DeMarco said. "We're just going to do the test tomorrow and that's the only update I have."
It's the same ankle that Ionescu hurt early in her rookie year, an injury that required season-ending surgery.
The star guard landed awkwardly during a drive to the basket and rolled the ankle early in the third quarter. She appeared to get her feet tangled with the Sun's Diamond Miller as she went up for a reverse layup.
Ionescu stayed down for a few seconds before getting up and waving toward New York's bench on the other side of the court. She walked with a slight limp back to the locker room.
"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."
Ionescu had six points in just under 16 minutes of play. She was 2-for-8 from the field.
Breanna Stewart said she talked with Ionescu after the game and that her teammate was in "good spirits."
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.
