Williamson suffered a mild knee sprain from the incident and he did not return to the game.
Williamson was wearing Paul George's shoes , the PG 2.5, when the incident occurred. On Thursday, George told reporters from the Oklahoma City Thunder's practice that he spoke to Nike and wasn't sure what happened.
"I don't necessarily know what happened, how it happened," George said. "Talked with Nike to see what went wrong, what happened with the shoe ... So, I don't necessarily know what happened. It's never happened to my knowledge before."
George said he takes pride in his shoe's success.
"I take pride in that. My shoe has been a successful shoe, not only in college, but in the NBA. A lot of people been in them, a lot of people been wearing them."
Williamson, the presumed No. 1 pick in the 2019 NBA Draft, appeared to have avoided major injury, though it's unclear if and when he will return to the court. Some have called for him to sit out the rest of the season to protect his NBA career.
George on Thursday wished Williamson well.
"I wanna wish him all the best," George said. "I don't know the severity of the injury right now, but just wish him all the best through the recovery, if it is something severe. Honestly, I'm just there for him through that time of being injured and being hurt. On a big stage, big game, him not being able to play that ... that's tough."
