The Scottish Premiership giants will take on Old Firm rivals Rangers in the semi-finals of the Scottish Cup at Hampden Park in Glasgow on Sunday afternoon.
Denmark international central defender Sviatchenko has a thigh injury, but Deila has suggested that the 24-year-old could be fit for the game.
"Erik can be ready,” the Norwegian is quoted as saying by Celtic’s official website. “It’ll be tight but he’s having progress. Final decision on Sunday. If he plays he’ll be 100%. We won’t take a risk."
Deila has also joked that Celtic have been training with 10 men in case there is a sending-off during the match, while making it clear that Rangers should know what’s coming.

Celtic will head into the game as favourites, but they should be aware of the threat that Rangers will pose.
Having already won the Scottish Championship and the Scottish Challenge Cup this season, Mark Warburton’s side will be determined to progress to the final of the Scottish Cup and maintain their chances of winning the treble this campaign.
