Thunder coach Scott Brooks did not indicate whether Perkins would miss any time due to the injury.
"We'll see how he feels tomorrow," Brooks said following Oklahoma City's 95-82 victory, according to The Oklahoman.
Perkins suffered the injury while battling for a rebound late in the second quarter. The 11-year veteran appeared to get his hand caught in an opposing player's jersey and then attempted to reset the bone.
Perkins did not return to the contest and was replaced by rookie Steven Adams, who finished with seven points and six rebounds.
