There's not a whole lot to add to this story, so we're deferring to Littmann's take: "Edwards got his foot caught in a lawn mower."
That would be Armanti Edwards of Appalachian State, he who gave Michigan such fits in the portentous 2007 season opener, and who despite GETTING HIS FOOT CAUGHT IN A LAWN MOWER is expected to make a full and speedy recovery in time for kickoff. Details at this point are sketchy, other than there being a LAWN MOWER involved, but we hope you'll find our artist's rendering as entirely plausible as we do:
Quoth 'Freek: "Revenge is a dish best served cold, and usually from lawnmowers and woodchippers." Carr's got nothing but time, man. Nothing. But. Time. [SFX: meeeeowwwSNAP!]
