Shortly after Alexander was spotted speaking to Kennedy, the NBA announced it was investigating the incident.
Alexander didn't offer much insight into his decision to confront Kennedy, but he did say he was "upset ... really upset," according to the Houston Chronicle's Reid Laymance and Jenny Dial Creech.
After dispatching the Thunder, Alexander's Rockets will return to the floor for the Western Conference semifinals against the winner of the first-round series between the San Antonio Spurs and Memphis Grizzlies.
