Mark Jackson loses MSG job after Knicks ban him from plane

Mark Jackson won’t be providing commentary for games on MSG Network, as the Knicks have objected to him being on the team’s chartered plane, sources tell The Post.

While MSG Network intended to have Jackson occasionally substitute for Clyde Frazier this season, Knicks management, led by team president Leon Rose, has halted the arrangement.

Sources indicate that the decision stems, in part, from a previous dispute between Jackson and an assistant coach.

“We weren’t able to work something out this season,” an MSG Network spokesman told The Post.
