Williams sprained his ankle when he stepped on the foot of Bulls point guard Nate Robinson in the second quarter. It looked serious at the time -- Williams had to be helped into the locker room -- but he played in the second half.
Deron Williams is seven assists shy of 5,000 for his career.
Williams, who was limited in practice Sunday as a result of the injury, is looking forward to taking on the Lakers.
"I mean, it's silly to think there's not going to be more excitement in the building and the atmosphere's not going to be good," he said. "It's a big game for us. It's another good team. Even though they're under .500, they're still a good team when they play well, and as of late they've been playing a lot better. This will be another good test for us at home."
Williams was asked how much tougher it is playing against Lakers shooting guard Kobe Bryant, given that Bryant's assists are up recently.
"I just think guarding Kobe in general is tough on anybody, because he's a threat to score 50 or he's a threat to get 15 assists," Williams said. "So you can't really just play him one way or another."
