The Kings announced the deal Thursday. The 7-foot-5, 360-pound Bhullar was called up from the team's NBA Development League affiliate, the Reno Bighorns.
The 22-year-old center could make his debut Friday when the Kings host the New Orleans Pelicans.
Bhullar was born in Toronto to Indian-born parents and played two seasons for New Mexico State. He twice won Western Athletic Conference tournament MVP and led the Aggies to back-to-back NCAA Tournament appearances.
Undrafted last year, Bhullar joined the Kings in training camp before signing with Reno. He's averaging 10.3 points, 8.8 rebounds and 3.8 blocks in the Bighorns' fast-paced system.
