Pau Gasol won't play Tuesday against the Rockets because of tendinitis in both knees.
A Lakers spokesperson also referred to the forward's condition as patellar tendinitis.
"The biggest thing with him was that he was trying to play hurt," said Mike D'Antoni, the Lakers' head coach. "And in this league, you just can't do that. We've got to get him healthy. Whatever it takes: one game, two games, 10 games, I don't know, day to day. But he's got to be healthy. It wasn't fair and he was trying to battle through some stuff and, in this league, you just can't do it.
"He just kept getting increasingly worse. He wasn't satisfied with the way he was playing and he just felt it was a question of he couldn't squat, bend down, get down, felt bad. And just talking about it, the easy conclusion is to just get better."
D'Antoni said that was a reason Gasol's minutes have been limited, saying he hasn't been running "fluidly." He went on to say, as always, it's the player's call to decide whether or not they can play. He also said Antawn Jamison will probably be in the starting lineup to replace Gasol. Another change in the starting lineup, he said, will come at the point guard position, where Chris Duhon will replace Darius Morris.
