Madison Bumgarner was placed on the 10-day disabled list by the Giants on Friday. The official press release:

The Giants today placed left-handed pitcher Madison Bumgarner on the disabled list with bruised ribs and a grade one or two left shoulder AC sprain. Bumgarner sustained these injuries yesterday during a dirt bike accident on the team’s off day in Denver, Colorado. Bumgarner is out of the hospital, currently resting at the team hotel and will be reevaluated next week. A pending roster move will be announced.

If this sounds serious, that’s because it might be. Harvard Medical School’s description of shoulder sprains have descriptions of a Grade I strain that range from “mild” with microscopic tears, to descriptions of a Grade II sprain as having a “slightly deformed” joint and visible ligament tears. A Grade III sprain is the worst one of all, but when it comes to a pitcher, I’m not sure how much comfort we should find in that.

More updates will follow, of course. And I was just thinking the Giants had it too easy this year.

UPDATE: According to Ken Rosenthal, Bumgarner is out for 6 to 8 weeks.

UPDATE II: Chris Stratton was recalled from Sacramento, which makes me think that Ty Blach is the replacement in the rotation. I’ll explain more in a bit.
