Mavs coach Rick Carlisle said he doesn't know how many minutes Beaubois will play in his first NBA action since last April, but it could be "significant" if backup point guard J.J. Barea is unavailable with flu-like symptoms and a slight groin injury.
Barea did not practice Tuesday and will most likely be a game-time decision. Either way, Beaubois' return from a broken left foot that has kept him out all season will be welcomed.
"No one's more excited than me," Carlisle said of the second-year guard. "I know that he can elevate our team in a lot of areas on the one hand. On the other hand, we're talking about a kid who has established only one line of consistency, that is playing 2-guard when Jason Kidd is playing the 1.
"So my job as coach, and our job as a franchise, is to get him in a position to be more consistent on an all-around basis, and that's going to be extremely challenging given all these circumstances."
Beaubois completed his second consecutive full practice session Tuesday. Carlisle reported that he looked good and has done everything he can to prepare to play in a game.
As he was Monday, Beaubois again was the last Mavericks player to leave the practice court after an extra shooting session.
He took Mavericks fans by storm last year with his dazzling speed and offensive abilities. Beaubois, who turns 23 in eight days, said he understands the lofty expectations set by fans and is motivated by them.
"That makes me want to work even more because they believe in me," Beaubois said. "That pushes me and I just want to help the team."
Carlisle tapped the breaks on talk of expectations.
"I would just caution everybody to just temper this with some realistic expectations," Carlisle said. "It's going to be hard coming off six months without playing. We'll see."
