Apparently, feigning unconsciousness is a new delaying tactic?

While taking the written rules test, which each person wishing to officiate high school soccer must do, I ran across this nifty redundancy:

If a player is deemed by the referee to be unconscious, or apparently unconscious, he or she may only return to the match with written authorization from a physician.
A.) True
B.) False

Hmm.  I'm not sure as to the reason why a player would want to appear unconscious without actually being so, but regardless, he or she will need a doctor's approval before rejoining the game. A.) True.
