WATCH: Knicks' Josh Hart 'Boos' as RJ Barrett, Immanuel Quickley Return to MSG

RJ Barrett and Immanuel Quickley received a warm welcome from the New York Knicks and their fans on Saturday night ... with one notable exception.

New York Knicks reserve Josh Hart had no love for his former teammates upon their return to Madison Square Garden.

The MSG faithful offered a warm welcome for former Knicks and current Toronto Raptors RJ Barrett and Immanuel Quickley, each of whom made their first return trip to Manhattan since the Dec. 30 trade that put OG Anunoby in blue and orange. Fans offered a loud, unanimous cheer when Barrett and Quickley were introduced in the Toronto starting five, previously booing fellow openers Scottie Barnes, Jontay Porter, and Gary Trent Jr.

But an exception among the cheers was Hart, who playfully booed as Barrett and Quickley took the floor in enemy colors. It's clear that Hart's taunt was all in good fun, as he previously hinted that he would jeer on X prior to the game. 

The Knicks lead the Raptors 59-57 at halftime at MSG. Barrett leads Toronto with 15 points on 6-of-10 while Quickley has earned eight points and assists each.
