Even Dustin Johnson's biggest sponsor hasn't heard from him

While the situation hasn't moved to Stage Anthony Kim yet, there is another sign that Dustin Johnson's "leave of absence" from golf is a genuine head-scratcher even for those closest to him.

Taylor Made-Adidas, the company that has elevated Johnson's image as one of the game's premier athletes and has made him one of the primary faces of the brand, has not heard from Johnson since he took his leave in August. Company CEO Ben Sharpe confirmed the surprising news to Bloomberg's Erik Matuszewski.

"We're looking forward to having a conversation with him and his team when the time is right," said Sharpe.

Johnson is signed with TaylorMade-Adidas through 2015.
