"Removing one's shirt after scoring is unnecessary and players should avoid such excessive displays of joy."Man, that would be a disaster if Villa went out on yellow card accumulation because he took his shirt off! What post-Victorian reason is that a reason for giving a yellow card? Is this an MLS rule or one adopted from FIFA?
I can't imagine Brandi Chastain got a yellow card for her celebration!
