U of Michigan to announce "historic event" at Michigan Stadium

The working assumption is that this is the long-rumored summer soccer game between Manchester United and Real Madrid in August. From Crain's Detroit:

Global soccer powerhouses Manchester United — wearing its new Chevrolet-sponsored jerseys — and Real Madrid will square off at Michigan Stadium in Ann Arbor at 4 p.m. Aug. 2, two sources with direct knowledge of the situation told Crain’s this week. The University of Michigan has scheduled a press conference for noon Friday to announce the game.

UPDATE: Confirmed.
