After pulling out of practice early Sunday because of back spasms, Duhon did not practice Monday, instead using the time to undergo treatment.
"Duhon has a little bit of a back issue," Lakers coach Mike D'Antoni said. "We’ll see (Tuesday). Treatment today but it’s more of a game-time decision (against the Philadelphia 76ers), probably."
With Steve Blake expected to be out another 3-4 weeks following abdominal surgery, Duhon had been serving as Steve Nash's primary backup. When Nash was out with a fractured left fibula, Duhon started nine games, averaging 6.9 points and 5.4 assists while shooting 42.1 percent on 3-pointers. For the season, Duhon is averaging 4.1 points and 3.7 assists in 22.8 minutes per game.
D'Antoni said he could use Darius Morris, who has been starting at shooting guard of late, as Nash's backup if Duhon can't play against the 76ers.
"Look at him, he can play," D'Antoni said of Morris. "He can play some minutes. He’s strong. He’s young. So, he can go."
Morris also started games this season at point guard while Nash and Blake were out.
