Philadelphia 76ers star Paul George suffered a hyperextended left knee early in the second half of Wednesday night's 117-111 loss to the Memphis Grizzlies and did not return.
Sixers officials said further testing will be done Thursday. It was the same knee that George hyperextended in the preseason, forcing him to miss the first five games of the regular season.
The injury marked the latest setback for the Sixers, who had stars George, Joel Embiid and Tyrese Maxey together in the starting lineup for the first time.
