Roberto Silvera
Roberto Carlos Silvera Calcerrada is an Uruguayan football referee.
He has been an International FIFA referee since 2003 and officiated several important fixtures since then which include the semifinals of Copa Libertadores in 2007 between Boca Juniors and Cúcuta Deportivo and again in 2008 between Boca Juniors and Fluminense.
Silvera also officiated the first leg of Copa Sudamericana final on two occasions.
He was selected for the 2007 FIFA U-20 World Cup in Canada but failed to pass a late fitness test and did not feature in the event. In 2011, he earned his first Copa América appointement after compatriot and controversial referee Jorge Larrionda was omitted from the selection.
During the 2011 Copa Libertadores group stage match between Santos and Colo-Colo he brandished a record 14 cards, five of them being red.
