Beaubois broke his left foot while practicing with the French national team in August and suffered a setback in October.
He has been through one full practice and stayed home for the first few days of the Mavs' current road trip, going through two-a-day workouts with Dallas coaching consultant Tim Grgurich.
Beaubois rejoined the team in Houston, where the Mavericks beat the Rockets 106-102 on Saturday night, and will practice twice this week.
Owner Mark Cuban has said several times that he's optimistic Beaubois would play before the All-Star break. The Mavericks play the Sacramento Kings at home Wednesday and the Phoenix Suns on the road Thursday.
"It's going to depend on the next four days," coach Rick Carlisle said. "We'll see where things are on Wednesday morning."
Beaubois said he feels no pain in the foot, but he has some trouble cutting after running in a straight line. His conditioning is also a concern after such a long layoff.
"I need to push myself to see actually what I can do and what I can't do," Beaubois said after participating in the Mavericks' morning shootaround Saturday. "It's my body, because it's been a long time, sometimes it's tough. But I'm good. I'm coming back, so it feels good.
"I don't want to get too excited. I'm waiting to get on the floor. It's day by day."
Beaubois, the Mavericks' first-round pick in 2009, had flashes of brilliance as a fringe rotation player during his rookie season. He averaged 7.1 points in 12.5 minutes per game, shooting 51.8 percent from the floor and 40.9 percent from the 3-point line.
The raw Beaubois barely played during the Mavericks' playoff series against the San Antonio Spurs. After getting only 10 minutes in the first five games of the series, he scored 16 points in 21 minutes of Game 6, keying a comeback that fell short.
A day after the series ended, Carlisle vowed that Beaubois would have a much more significant role this season.
"I'm not worried about that," Carlisle said. "First, we've got to get him ready to play, then it will become a conversation. At this point, he's got to get himself ready. We'll see what's what when that happens."
