Yikes! Reminds me of when I caught a pedal to my left shin during a high-speed crash in mud at Mt Snow back in 2000. The result was 30 min of scrubbing by the nurse at the mtn care center and 14 stitches along with a bottle of antibiotics with the warning, "I'm pretty sure I got all of the mud out, but it's hard to know for sure, so take these for a week."
While I was in the care center Pro practice had started and before I left I was joined by Steve Peat (separated shoulder, I think) and a very young Mick Hannah (broken collarbone).
