Tevez was visiting his half brother Juan Alberto Martinez, who is at the maximum security Bouwer's prison in Cordoba. Martinez is serving a 16-year sentence for armed robbery.
Tevez decided to play a little game against some of the in-mates, where he hurt himself.
While the player did not initially reveal the way he got hurt, the news eventually got out.
Tevez will miss a month of action, and his club Boca Juniors are furious at his conduct.
