The 24-year-old was forced to miss a practice session on Monday as a precaution, but he is confident of making an even greater impact as Oklahoma aim to make it 2-2 in game four.
"The good news is I'm not feeling worse, so that's good," Ibaka told members of the media. "I'm sure every day I'm going to feel better every day, but I'm not expecting to feel much better yet tomorrow.
"One thing I know, I expect to do a better job."
Ibaka was seen limping on a number of occasions in game three after he was originally ruled out for the rest of the season with the injury.
