After sitting out the fourth quarters of the last two games, Carlos Boozer and Joakim Noah made key contributions late to help the Bulls hold off the Boston Celtics on Friday.

Noah had four points, three rebounds and two blocked shots in the fourth quarter to finish with 10 points, 12 rebounds and four blocks, while Boozer contributed two rebounds in the fourth and finished with 12 points and eight rebounds.

''I love the way Jo was active tonight blocking shots and going after the ball,'' coach Tom Thibodeau said. ''Then his offense came around. When he plays like that, it's good for us.''

Before the game, Thibodeau said he's not considering changing his starting lineup despite Taj Gibson and Omer Asik playing critical moments against the Minnesota Timberwolves and Washington Wizards.

''I feel like I can still do better, but I'm not going to lie: It felt pretty good to be out there competing,'' Noah said.

While Boozer's and Noah's production may be down, Thibodeau said having options on the bench is a luxury during this, of all seasons.

''It's one of our strengths: quality bigs up front, and where we are in our schedule right now, it's hard to play big guys extended minutes,'' he said. ''The fact that we have great depth allows us to rotate all four of those guys. They've all done a good job for us.''
