Yahoo! Sports' Adrian Worjnarowski reports that the Knicks head coach has resigned, citing a source who said the decision is based on "conflicting visions of club's future."
According to Wojnarowski, assistant coach Mike Woodson will take over as the team's interim head coach.
Sports Illustrated's Sam Amick suggests that it D'Antoni's departure from the team was a "mutual decision."
Whatever the reason, D'Antoni's tenure was under siege of late, stemming over frustration with the team's play with Carmelo Anthony back in the lineup.
The Knicks had captured the country's attention earlier this year, but after Anthony returned the lineup to play alongside Jeremy Lin, the team has sputtered and fallen out of the playoff race in the East with six straight losses.
Deadspin reports a source has indicated D'Antoni could be headed to Washington or Charlotte, "otherwise he would not have left."
