The Chile legend was banned for the rest of the 2015 Copa America after his famous “Finger of God” intrusion on Uruguay great Cavani.
But now Jara has turned his back on notoriety and hopes to go viral for all the right reasons.
The 115-cap defender, 37, is leading a drive by TNT Sports Chile called “Get your prostate checked, champion” at the huge derby between his old clubs Universidad de Chile and Colo Colo on September 3.
He told a promotional video: “I’ve been dodging the finger issue for eight years, but now that the Superclasico is coming up, the time has come.”
Next month’s big match falls on National Prostatic Testing Day.
Jara found worldwide notoriety for his inappropriate act on then-PSG striker Cavani, now 38, who later played for Manchester United.
Both international stalwarts are still playing top-flight club football.
Argentine giants Boca Juniors unveiled Cavani last month and Jara has been with home-country club Coquimbo Unido since last year.
And despite Jara’s three-game suspension in 2015, hosts Chile still went on to win the Copa America, beating Argentina on penalties in the final.

Jara now appears on a website where the public register fans of Universidad de Chile or Colo Colo aged over 45 for a free prostate antigen test.
Francisca Mora, Marketing Manager of Warner Bros. Discovery, said: “Almost 70% of our viewers are men, and a significant number are over 45 years old.
“With that in mind, and to take care of an important member of this great football family, we take advantage of this Superclasico to make a call for prevention and self-care of prostate cancer.”
The Chile Skin Cancer Foundation are also taking part in the campaign.
Its president Dr Bruno Nervi pointed out that 40% of prostate cancer diagnoses are made in a late stage, leading to more than 2,000 deaths a year in the country.
