Giannis Antetokounmpo will be assessed ahead of the All-Star Game after suffering a wrist injury during the Milwaukee Bucks' win over the Chicago Bulls on Thursday.
The two-time NBA MVP grimaced as he left the court during the second quarter of a 112-100 victory.
Antetokounmpo had broken the record for the most assists by a Bucks player, moving beyond Paul Pressey's tally to 3,274.
The Greek forward is due to play in the All-Star Game at Vivint Arena in Salt Lake City on Sunday, but it remains to be seen if he will be fit.
Bucks head coach Mike Budenholzer said he had "no idea" if Antetokounmpo will play this weekend, but an X-ray was "clean" and initial reports were "hopeful".
He added: "We'll just see how he feels tomorrow, see how he feels the next few days and continue to evaluate it."
Budenholzer continued: "He's a guy that's attacking the basket all the time. He's fearless. He takes a lot of falls, so you kind of learn to just expect him to always just bounce back up, and that’s what we're hoping for from this one."
Brook Lopez scored a season-high 33 points and Jevon Carter poured in 22 as Milwaukee reeled off a 12th successive win to improve to 41-17, sitting second in the Eastern Conference.
