Israeli footballer (sounds better than "soccerer") playing in Spain, Sean Weissman, wore a black ribbon on his arm in memory of the 45 victims of the Meron tragedy, and when he scored a goal, instead of the usual celebration he stopped and help up his hands to signify 45, dedicating the goal to the memory of the 45 victims. 

As an aside, the goal was later disqualified and revoked on some technicality. Those damn antisemites! :-)
