Tim Duncan, Kawhi Leonard out tonight?

San Antonio will be without Tim Duncan (sore left knee) and Kawhi Leonard (left knee contusion) in its home game tonight with New Orleans, writes Dan McCarney of the San Antonio Express-News. Both are considered day-to-day. How will this affect the Spurs' roster for tonight's game against the upstart Hornets, who have won seven of their last nine games and knocked off the Spurs at home back on Jan. 7?
