He wasn't on the roster yesterday and now it's official:

Sources close to the U-M football program have confirmed that true freshman Davion Rogers, a linebacker out of Warren, Ohio, is no longer with the program. Rogers, a 6-6, 205-pounder, came to U-M out of Warren G. Harding High School.

No idea why. Rogers reportedly had a Clearinghouse issue earlier this fall so it may be related to that. He wasn't going to play this year since he's skinnier than Roy Roundtree but seemed to have a lot of long-term potential; his departure is another hit to the APR, which seems like it will inevitably drop below 925 now at some point, and another hit to the depth of the defense. Michigan's most recent class has now lost Austin White, Demar Dorsey, Conelius Jones, Antonio Kinard, and Davion Rogers just a month into their freshman years. At some point this has to stop happening, right?

UPDATE: The News confirms and gets someone saying that it was a clearinghouse issue, which means it shouldn't impact Michigan's APR. Tim pointed out that if he was out before the drop/add deadline he wouldn't have counted against the APR anyway. Still, Michigan and Rodriguez have to do a better job of identifying players who will get on campus.
