underdog
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">one expected to lose</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for underdog that I've seen before include "Competitor expected to lose" , "One with little status" , "Contestant who's not expected to win" , "One of low status" , "One at a disadvantage" .)
