The Slovenian champions were originally ordered to close their South Stand - where their most passionate fans gather - at their Ljudski vrt stadium.
They were found guilty of racist behaviour after a game against Bosnians Zrinjski because their fans were waving Celtic crosses - which UEFA deemed to be a symbol of a 'white pride' neo-Nazi group.
But after Maribor contested the charges, UEFA have now relented and allowed the stand to only partially be closed. It means their capacity will be reduced by only 1500 for the game.
Maribor director of football Zlatko Zahovic said: "We don't believe our supporters displayed any racist symbols and, late on Monday night, we received a favourable decision from UEFA.
"Now the South Stand will not be completely closed and we are able to sell tickets for sections in that stand. The total capacity now will be 11,424."
