Howard met individually with each player Monday, when the team did not have a practice.
The Wolverines are on the NCAA Tournament bubble with a 17-13 overall record and 11-9 mark in the Big Ten.
With coach Phil Martelli filling in for Howard, Michigan closed the regular season with a win over then-No. 23 Ohio State on the road Sunday.
Howard will be back on the sideline Thursday in Indianapolis, leading the eighth-seeded Wolverines against ninth-seeded Indiana in the conference tournament quarterfinals.
