New York originally reached a 10-day contract with Arcidiacono on Monday under the league’s hardship provision. However, once Mitchell Robinson and Jericho Sims cleared the health and safety protocols, the Knicks only had two players remaining in the protocols and already had two hardship additions on their roster.
Wednesday marked the first day that teams were permitted to begin signing players to conventional 10-day deals. New York had an open roster spot after waiving Wayne Selden and Denzel Valentine this week.
Arcidiacono, 27, spent his first four seasons with the Bulls, averaging 4.8 points, 2.0 rebounds and 2.2 assists in 207 games. He signed a training camp deal with the Celtics in September, but was waived before the start of the season and has been playing for Boston’s G League affiliate in Maine.
