John O'Korn to the forefront [Eric Upchurch]
Per a source, Wilton Speight has broken his collarbone and is out for the remainder of the regular season. Depending on the exact nature of the issue it is possible he could return for the bowl game.
FWIW, when Tony Romo broke his collarbone last year he was projected to be out eight weeks, and was supposed to be out 6-8 after collarbone surgery in May. Speight had a bad collarbone break in high school—that's why he's a year older than most of his class—and may be in line for a similar surgery.
Michigan will almost certainly go with John O'Korn in Speight's stead; in scattered snaps this year he's 13/18 for 114 yards and two TDs. O'Korn's mobile enough to incorporate some designed QB runs, so we've got that going for us.
