The NBA's new concussion policy, which was instituted at the start of training camp this season, mandates that players with diagnosed with concussions must undergo neurological testing and pass a series of exertion protocols that include riding a stationary bike, jogging and individual basketball skills. The policy also mandates that players must remain symptom free after each test, and teams then must consult with Dr. Jeffrey Kutcher, the director of the NBA's concussion program, to determine when a concussed player can return.
Harden, the Thunder's sixth man, is averaging 16.8 points, 4.1 rebounds and 3.7 assists on 49.1 percent shooting, all career-highs. The third-year shooting guard out of Arizona State is projected to win this year's Sixth Man of the Year award in a landslide.
The Thunder is 2-0 without Harden in the lineup, with wins over New Orleans and Sacramento.
