The Boston Celtics will face quite the test Thursday.

One night after a tough loss to the Detroit Pistons at TD Garden, the C’s are in Chicago to take on the Bulls, who are riding a five-game winning streak and own the No. 2 seed in the NBA’s Eastern Conference with a 21-12 record.

Boston will have to battle the Bulls without their head coach, as Brad Stevens will miss Thursday’s game to attend to a personal matter.

Here’s how to watch Celtics-Bulls:

When: Thursday, Jan. 7, at 8 p.m. ET
Live Stream: Watch TNT
