He started at center and finished with 8 points, 2 rebounds, 4 blocks and 2 assists in the Lakers' 106-96 win, which brought them back to .500 at 24-24.
"For the most part I felt fine, felt great out there and the first couple minutes the adrenaline took, and after that the wind caught up to me," Davis said. "When I caught my second wind, I was fine for the rest of the game."
Coach Frank Vogel said pregame there was no set minutes level for the All-Star big man, but the Lakers had a range they wanted to keep him in Tuesday night. Davis ended up playing 25 minutes.
"I don't know about the whole minute restriction thing, I think for me that might come off," Davis said. "Might tell [coach Vogel] I don't need that, but we'll see."
His return is a boost for a team that has played below expectations all season and sits seventh in the Western Conference.
"He just makes our team so much more complete, our length defensively, our ability to really get up in people's faces because we know we got him at the rim or our ability to switch a lot of things because he can literally guard 1-through-5," teammate LeBron James said. "Offensively, it just attracts another set of eyes off of myself, off of [Russell Westbrook], off of [Carmelo Anthony], off of [Malik Monk]. Off everybody because he's such a dynamic player."
Davis had not played since Dec. 17. The Lakers went 7-10 in his absence.
