New Orleans has five pivotal away games
The losses couldn't come at a worse time for the Hornets, who are battling to hold on to the fourth seed in the Eastern Conference playoff race.
Davis, sidelined with a sprained left ankle, was not with the team for Friday night's home game against Phoenix.
Floyd said Davis went to Los Angeles to be with his sick grandmother and would rejoin the team next week. But the point guard is in a lot of pain and could be sidelined as long as two weeks, Floyd said.
Mashburn, out since aggravating a right knee injury on March 7, has new swelling in his knee, Floyd said.
"I don't know that there's any return date that's probable right now," Floyd said.
Davis leads the team in scoring (23 ppg), assists (7.6) and steals (2.4).
Mashburn is averaging 20.8 points per game. He has played in only 19 games because of the knee injury.
The Hornets will play the Los Angeles Lakers, Utah, Sacramento, Portland and Seattle on their upcoming road trip.
New Orleans entered Friday night with a 1½ game lead over Milwaukee for the fourth seed in the East.
