DALLAS -- Guard Rodrigue Beaubois hobbled off the court in pain near the end of the Mavericks' practice, having turned his left ankle again.
"We hope he's going to be OK and it's not serious," coach Rick Carlisle said.
Beaubois sprained that ankle in the Mavs' exhibition opener in Berlin and missed the next three preseason games.
Injuries have marred the 2009 first-round pick's career. After a promising rookie season, Beaubois broke his foot while training with the French national team, an injury that required two surgeries and sidelined him for most of his second season.
This season got off to an encouraging start for Beaubois, who is backing up Darren Collison at point guard. He had 11 points and five assists in 17 turnover-free minutes in the Mavs' win over the Lakers, prompting Carlisle to say the performance showed Beaubois' potential.
