I believe the answer is:

<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">part of a goal</span>' is the definition.<br/ ><span class="explanation-format__explanation">('crossbar' is part of 'goal')</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for crossbar that I've seen before include "Post connecting goalposts" , "It may support rider" , "Goal's top member" , "Horizontal beam over goal posts" , "what one may tip over?" .)
