Defender Luiz Otavio was the match-winner against Lanus, but he should have been suspended and the victory has been stripped from the Brazilians
Chapecoense's Copa Libertadores hopes have come to an end after the Brazilian side were punished for fielding a suspended player.
CONMEBOL announced the sanction on Tuesday, with Chapecoense knocked out of the Libertadores as Lanus were awarded a 3-0 win after defender Luiz Otavio was deemed ineligible to play on May 17.
