Karnataka, level with Delhi on six points, are now third in the Group ahead of Delhi, after their thumping five-wicket win against Andhra and will begin as favourites at the Jamia Milia Islamia ground.
Delhi, who have their last chance to exploit the home advantage, will look for a positive result to regain their second spot in the table, which they lost after conceding two points to MP in the drawn match.
Delhi will play their last two matches against Bengal and defending champions Mumbai, who are currently the Group leaders with 12 points.
"All the matches are crucial for us, but tomorrow's match is more crucial because our next two matches are at away venues against Bengal and Mumbai," Delhi coach Madan Lal said.
"We have yet not decided on the team composition. We will decide it only before the start of the match, but we may include three spinners and two medium fast bowlers as the wicket might start turning after the first day," Lal said about an otherwise pace-friendly Jamia track.
Captain Ajay Jadeja would once again miss opener Gautam Gambhir, who is doing national duty in Bangladesh. The prolific left-hander had played against MP.
