Coach Tom Izzo said he expects Harris to play Tuesday against North Florida.
"I would call him questionable/probable," he said. "I think he'll play. I think what we gotta look at now is if he is going to have a little soreness in that. …
"We will know a little bit more (Monday night) after the next practice and see how he responds."
The sophomore tweaked his right ankle early against North Carolina a couple weeks ago. The ankle was in a hard cast for part of last week.
Izzo said Harris took part in "90 percent of things" in practice Sunday.
"I don't wanna put anything on one guy," Izzo said, "but I've said all along as far as a guy that can change the game at both ends he just has such a great understanding of the defensive stuff that he helps people. (Sunday's) practice was just different."
The Spartans' coach also said having Harris back impacts the rest of the guards and that is a reason to try get him back on the court sooner rather than later.
"I told him last night whether he likes it or not, he might be the leader of the team because he influences other people," Izzo said. "Everybody respects him and he is one of the hardest workers and one of the best players and that's a great combination when that happens."
Harris also sat out the Spartans' win against Mount St Mary's on Nov. 27 resting his ankle.
