A team spokesman said coach Jay Wright benched the pair as a "minor teaching point."
Their punishment didn't last last long. Reynolds sat out the first 4 minutes of Thursday's game, and Fisher checked in about 30 seconds later.
Reynolds leads the second-seeded Wildcats in scoring with 18.5 points a game and Fisher is second at 13.7 points. Both had started every game this season.
Wright held forward Taylor King out the season finale against West Virginia for the same "teaching point" reason.
Reynolds and Fisher led the Wildcats onto the court and participated in all pregame drills.
