Monty Williams is taking the rest of the season to grieve the loss of his wife.
The Thunder assistant coach will not return to the team this for the remainder for the season to spend time with his family and friends, the team announced Friday.

Williams' wife, Ingrid, died in a car accident last month after another vehicle crossed the center lane and hit her head-on.
The Thunder, who have a 44-20 record, will head to the playoffs in April without Williams.
"I have really enjoyed my relationship with Monty, and clearly we will miss him, but we value and embrace that it is critical he is there for his family at this time and our focus is on doing whatever we can, in any small way, to help him," coach Billy Donovan said. "He and his family will continue to be in our thoughts."
