According to ESPN.com's Ian Begley and Ramona Shelburne, a source indicated the decision was made "a while ago," which means Jackson stands to remain in his current position through the 2018-19 campaign.
Per Begley and Shelburne, Knicks owner James Dolan said during a Feb. 10 interview on ESPN New York 98.7 FM's The Michael Kay Show that he planned to honor Jackson's five-year deal "all the way to the end."
The Knicks have struggled during Jackson's tenure, as they are just 80-166, and recently completed a 2016-17 campaign that saw them finish 31-51.
Jackson also made headlines for seemingly slighting Carmelo Anthony in February with a tweet in response to an article by Bleacher Report's Kevin Ding.
That hasn't translated to success in his current role, as New York hasn't reached the playoffs since 2012-13.
