For those of you who don't remember, Nancy Kerrigan's leg was broken in an attack orchestrated by another skater (Tonya Harding) back in 1994.
Kristi apparently wasn't thinking when she tweeted "break a leg".. but her followers were quick to respond --
OK, maybe this one with Tonya Harding went a bit too far...
Kerrigan was gracious, seemingly oblivious (or choosing to look that way) to the word choice..
Yamaguchi's spokesperson says "Kristi loves Nancy" and "no ill will was intended."
