Coach Rick Carlisle said Saturday the injury is not considered serious.
"We'll see how he's doing for tonight and tomorrow and go from there," Carlisle said.
Though he does not have a history of back problems, durability is a major concern with the 30-year-old Kaman, who signed a one-year, $8 million deal with the Mavericks this offseason. He has missed significant time due to injuries in four of the last five seasons.
Kaman's injury problems have primarily been with his left foot and left ankle.
Kaman, whom Dirk Nowitzki calls "the best offensive center I've ever played with," made his lone All-Star appearance in 2009-10, the last season he stayed healthy.
He averaged 18.5 points and 9.2 rebounds that season and has career averages of 11.9 points and 8.3 rebounds.
