Young, who suffered a non-displaced fracture of the patella and a bone bruise in his left knee Feb. 5 against the Cleveland Cavaliers, played 20 minutes against the Brooklyn Nets on Sunday but did not participate in shootaround Tuesday morning in Indianapolis.
"I'd say I was playing through adrenaline," Young said of the Nets game, when he scored 10 points on 3-for-4 shooting. "[Monday] I felt more pain once I settled down."
The Lakers are officially listing Young as day to day because of soreness in his knee.
Young was cleared by Lakers physician Steve Lombardo to return last week and went through three practices before getting back in the lineup. He opted against getting a follow-up MRI on the knee.
"I kept telling myself I think I can play," Young said. "It wasn't an ACL injury or nothing where I really had to sit out. I felt like if I was 80 percent, I could play. That's what I was feeling."
Young plans to fully recover before attempting another comeback.
"It's something that can get worse or cause other injuries, that's why they want me to wait until I'm pain free," said Young, who added his knee felt "a little bit worse" after the Nets game.
Said coach Mike D'Antoni, "We're going to back him off a little bit. First time out, probably got a little sore. Nothing to worry about, but there's no reason to push him."
Young said "hopefully" he can play Friday when the Lakers host the Sacramento Kings but would not commit to that date. His rehab will consist of icing the knee and rest.
"I wish I was in L.A., I don't want to see these guys no more," Young said jokingly. "It's depressing ... I can't be in Indiana just talking to these dudes."
The Lakers will go with the same small starting unit they used against the Nets when they play the East-leading Pacers on Tuesday. Pau Gasol will start along with Wesley Johnson and Kent Bazemore in the frontcourt, with Jodie Meeks and Kendall Marshall in the backcourt.
"They like to play big, obviously, and we're going to run," D'Antoni said. "There will be a meeting of the minds and there will be a change made. Either they're going to have to go small or we're going to have to go bigger, so we'll see who wins that little battle. We got to be relentless in speeding them up and getting into them. If it looks good, we can stay. If they start to pound us and catch us on the ropes, then we got to change up.
"If we just match up with them, they're going to kick our butts. We're not doing that."
