Jonathan Feigen of the Houston Chronicle provided the status update ahead of the nationally broadcast matchup between two of the Western Conference's top four teams.
Harden suffered the injury during the Rockets' double-overtime victory over the Los Angeles Lakers on New Year's Eve. He missed the team's last seven games while recovering.
"It just feels good to be back out here around your teammates and that good energy and just hooping again," Harden told reporters Wednesday. "Two-and-a-half weeks felt like a very long time. I look back at it and just say it was something I needed mentally, physically and to just get my mind right. Obviously, my body is well. Hopefully I won't have to go through that again."
The five-time All-Star selection was enjoying another terrific season for Houston before the setback. He's averaging an NBA-best 32.3 points to go along with 9.1 assists, 5.0 rebounds and 1.8 steals per game across 35 appearances.
