The Detroit Institute of Arts will be cleaning up and repairing the sculpture Wednesday.
It's part of an effort to conserve the "Monument to Joe Louis." It is a sculpture of the famed boxer's art and fist.
Crews will perform minor structural work to the 24-foot bronze sculpture, hang new cables and clean the surface.
The 30-year-old sculpture is part of the DIA's collection and is treated about every 10 years.
The monument to the late heavyweight champion was commissioned with a $350,000 grant from Sports Illustrated magazine. It was unveiled in 1987.
