The Chile defender poked Uruguay's Edinson Cavani in the bum during the quarter-final, provoking the striker to react and get sent off - the hosts went on to win 1-0 to book their place in the semi-final.
But Jara has previous.
Video has emerged that shows the 29-year-old, who spent four years in England with West Bromwich, poking another striker in the bum as provocation.
Back in 2012 it was Gonzalo Higuain of Argentina who found himself in the firing line.
Unlike Cavani, the striker - a target of Arsenal - did not react and went on to score as Argentina won 2-1.
