Rodgers axed the three players for last weekend's 3-2 Premier League defeat to West Ham after they broke Covid-19 protocols by attending a party at Perez's house.
But the Leicester boss said they were back in contention for today's semi-final and had a chance to restore their damaged reputations.
"That is what they are very determined to do," he said. "These guys have made a great contribution for us, we are also in the position we are because of them.
"They made a mistake and in football there will be a choice again, at some point in their careers, and hopefully they'll make a better choice.
"We always have to look forward and it's in the past. The best way they can do that as a player is by their actions on the field."
