Rookie guard Doron Lamb was assigned to the Fort Wayne Mad Ants of the NBA Development League on Saturday.
Coach Jim Boylan confirmed the move after the Bucks practice session at the Cousins Center. Lamb practiced with the team but was scheduled to report to Fort Wayne on Sunday.
Lamb will practice with the team and play in road games against Los Angeles on Wednesday and Bakersfield on Friday.
"It's an opportunity for him to play a bit," Boylan said. "Practice is practice and working out is working out, but there's nothing like playing in a game. This is not a punishment by any means.
"This is to make him better and develop him. He shows great potential. We're excited about his future. At the same time, there's really nowhere for him to play right now. A lot of teams are using this open enrollment for the D-League teams where you can send a guy down and bring him right back.
"There was a time you could only do it a couple times a year. Now it's unlimited. So everybody's taking advantage of it."
Lamb was the 42nd overall pick in last June's draft after spending two years at Kentucky.
"I'm going to go out there and get a lot of playing time and show them I'm ready to come back," Lamb said. "Just work hard."
Fort Wayne is the D-League affiliate of the Bucks, Detroit Pistons, Indiana Pacers and Charlotte Bobcats.
Lamb has appeared in 23 games this season and averaged 3.4 points and 12.2 minutes. He saw some backup time in the backcourt when Beno Udrih was injured.
But Udrih has returned from a sprained right ankle and scored 15 points against Detroit on Friday.
"He's coming along nicely," Boylan said of Udrih. "Having him on the bench, he changes the rhythm of the game a little bit. You need that from your bench guys.
"He's done a great job for us all year."
The Bucks leave town later Saturday to start a four-game, seven-day trip. They open against Toronto in a matinee game at noon (Milwaukee time) Sunday.
Boylan said Monta Ellis was able to take part in the Bucks' light practice session Saturday. Ellis twisted his left ankle against Chicago on Wednesday but had 13 points and five assists in the Bucks' 103-87 loss to Detroit on Friday.
"He was fine," Boylan said. "He looked good and moved around well."
