Knicks center Joakim Noah got into a physical altercation with coach Jeff Hornacek that led to his leave of absence, according to Stefan Bondy of The New York Daily News.

Their long-running disagreement over playing time became heated at a practice following a January 23 game against the Warriors in which Noah logged just five minutes. They had to be separated after Hornacek shoved Noah, Bondy reports.

Noah is currently on a leave of absence, which Knicks officials describe as mutual. The team tried to trade him before the February 8 deadline, but there were no takers because of his hefty contract, which still has two more seasons and nearly $38MM remaining.

Trying to reach a buyout agreement is another option, but it’s one the Knicks have been opposed to. If Noah does become a free agent, the Timberwolves are an obvious potential destination with Noah’s former coach Tom Thibodeau running the team.
