Kevin Durant has a fractured right foot and the NBA's MVP seems likely to be sidelined for at least the start of the season.
The Oklahoma City Thunder said Durant informed the team of "discomfort'' in his right foot after practice a day earlier. He underwent tests and the team said in a statement he was diagnosed with a "Jones'' fracture - a broken bone at the base of the small toe.
It's unclear how the injury happened.
The Thunder said traditional treatment requires surgery, and recent NBA cases have resulted in a return to play in six to eight weeks.
Durant won the scoring title last season, collected his first MVP award and led the Thunder to the Western Conference finals.
He skipped playing for the US national team in this summer's Basketball World Cup so he could get additional rest.
He played in two preseason games before complaining of pain.
