The popular Australian has missed the past five games with a strained right hamstring for the Bucks, who have gone 3-2 without him and sit seventh in the eastern conference.
"Delly's cleared to return tomorrow," the Bucks tweeted on Sunday.
Dellavedova trained with the side at the Cousins Center on Saturday.
"I feel good," Dellavedova told the Milwaukee Journal Sentinel.
"I'm looking forward to getting out there. It's never fun watching."
Dellavedova started 30 games for the Bucks before suffering the injury in the win over Detroit on December 28.
Coach Jason Kidd admitted the Bucks have missed the hard-nosed Dellavedova after his spot was taken by rookie Malcolm Brogdon.
"Just his toughness and his execution," Kidd said.
"Malcolm has done an excellent job. But having Delly, another point guard, we've been short-handed. So it's good to get Delly back."
