The Oklahoma City Thunder announced today that center Steven Adams is out for tonight’s contest at the New York Knicks and has been placed into the NBA’s concussion protocol. The injury occurred with 32 seconds remaining in the first overtime of last night’s 119-117 triple overtime win over the Philadelphia 76ers, when Adams suffered a blow to the head while defending Sixers center Joel Embiid.

Per the NBA’s Concussion Policy, Adams will now begin the NBA-mandated Return-to-Participation Protocol.
