They will then start on a clean slate and be available again as the title race heats up.
Downs coach Pitso Mosimane said there is nothing wrong with what they did.
"We have to be honest and understand that we have a lot of yellow cards," he said.
"It doesn't look good or professional but everyone is doing it. Tell me of a team that hasn't done that. If you want to chase the league then you must clean your yellow cards. It's not cheating."
Celtic coach Lehlohonolo Seema also conceded that it's part of the game.
"If they had players on yellow cards and they want to clear them there is nothing we can do.
"It's always happening. I can't complain and say they wasted time. It's part of the game."
Sundowns players' deliberately inviting yellow cards 'part of the game', says Pitso Mosimane
Was it unsporting behaviour or did Mamelodi Sundowns just box clever?
Football fans have reacted in different ways to what unfolded when four Sundowns players halted the game and took turns to intentionally get themselves yellow cards.
After the 80th minute in their clash with Bloemfontein Celtic, Downs players got themselves in trouble with referee Cedric Muvhali.
Gaston Sirino, Sibusiso Vilakazi, Hlompho Kekana and Mosa Lebusa play acted to pretend they were taking a corner kick but only to waste time and force a yellow card.
Sundowns were 2-1 ahead in the match and went on to win it. The players have now accumulated four yellows and will be suspended for the clash against minnows Vaal University of Technology in the Nedbank Cup on Sunday.
