Knicks owner James Dolan is going ahead with his plan to have Mills remain as permanent team president, the New York Post reported Tuesday.
Mills was in charge of the team's front office for a few months before Jackson was hired, but he was demoted when Jackson was brought on board.
He became the interim head of the front office after Jackson left with the belief that someone would be brought in from outside to fill Jackson's shoes. There reportedly have been no negotiations between Dolan and Mills on a contract for the job.
When Jackson left, initial speculation was that the Knicks would go after Toronto Raptors president Masai Ujiri, but that never panned out.
The Knicks then pursued former Cleveland Cavaliers general manager David Griffin, but the two sides could not reach agreement on Griffin's exact role.
In the meantime, Mills signed Tim Hardaway Jr. to a four-year, $71 million deal.
So now it appears Mills will be running the Knicks, and he is expected to have final say on personnel decisions, according to the Post report.
The Knicks will continue to schedule interviews for the No. 2 man under Mills.
