Andre Iguodala was cleared of serious damage after undergoing an MRI scan on his calf, but the Golden State Warriors veteran is a doubt for Game 4 of the Western Conference Finals.
Iguodala departed after feeling tightness in his left calf in the opening quarter of a 110-99 victory over the Portland Trail Blazers on Saturday.
The 35-year-old guard's scan came back as negative, but he may not feature when the defending champions - who lead 3-0 - attempt to wrap up the series on Monday.
Head coach Steve Kerr says Alfonzo McKinnie is capable of stepping up if Iguodala is unavailable.
"We'll have to have more minutes from him, but we're confident he can do the job." said Kerr.
Stephen Curry echoed Kerr's sentiments.
He said: "Injuries are a part of the game, but we have guys that are capable and can step up. It will require Alfonzo having a few more minutes, Jonas [Jerebko], J.B. [Jordan Bell] playing the solid basketball he did on Saturday night."
