Kaman, who continued to experience headaches for several days after passing the cognitive testing portion of the NBA's concussion protocol that he referred to as "the stupidest test ever," declared himself ready after Saturday's practice.
"Hopefully, I'll get a few minutes tomorrow," Kaman told reporters. "The headaches are gone, so I'm clear. I'm going to play. It's been too long."
Kaman, who was injured during the Mavs' Jan. 28 practice, fully participated in two practices this week after being medically cleared. The Mavs wanted him to practice twice before playing in a game.
"And the next game to come back to is (against) Dwight Howard," said Kaman, who is averaging 12.4 points and 6.2 rebounds per game in his first season with the Mavs. "There are a lot more easier matchups than Dwight Howard. But it is what it is. I just need to get out there and play."
It isn't clear how Kaman will fit in the Mavs' crowded center rotation. He was demoted to the bench in the two games before his injury, playing season lows of 12 and 11 minutes.
Rookie second-round pick Bernard James, who had seven blocks in Friday night's win over the New Orleans Hornets, has established himself as the starter, playing primarily in the first six minutes of each half. Veteran Elton Brand, the Mavs' best post defender, is getting the bulk of the big man minutes. Brandan Wright has been effective recently in limited minutes.
