Well, I've had this cut on my knee since I fell on my bike on saturday, and it's really been bothering be because I can't bend my knee too far. I haven't been able to run all week, and I have a cross country 2-mile stage race in 2 days! it's going to suck.
Anyway, here's a picture of it (it's been healing for a week, so it's gotten smaller)

sorry for the huge picture.
Have you ever had any bad injuries that put you out of physical activity (like that one)?
