The Knicks are open for business — kind of.

On Friday, the Knicks announced they would reopen their Tarrytown training facility for voluntary individual workouts for players on the same day it appeared their season may be over.

The reopening comes seven days after Gov. Andrew Cuomo announced teams in the state could reopen their training facilities for players.

“The Knicks re-opened the MSG Training Center today for voluntary player workouts,’’ the team announced in a statement. “As the safety of our players and staff remains our priority, we will continue to follow the guidelines established by the State of New York and the NBA.”

Under NBA guidelines, only four players are allowed inside the facility at any one time for individual workouts.

Most of the Knicks players and coaches left town during the lockdown. The opening, according to a person debriefed on the situation, gives their players a chance to safely work out if they so choose — even if there are no more games this season for the Knicks.

Taj Gibson and Mo Harkless were two Knicks who stayed in New York during the pandemic after the season shut down March 11. Mitchell Robinson has come in from New Orleans to train, according to his Instagram. Some coaches also are expected back in town to survey the situation.

The Knicks’ chances of restarting the season are “a long shot,’’ according to a source, as the league is leaning against bringing back all 30 teams.
