Monza and Verona failed to make the most of good situations, while VAR rescued the referee from a howler when he mistakenly awarded a penalty.
Samuele Vignato and Gianluca Caprari were still out of action for the hosts, while Hellas had Tomas Suslov suspended, with Alessandro Berardi and Juan Manuel Cruz injured.
January signing Swiderski got his first start for Verona and in the opening minutes his back-heel flick sent Darko Lazovic down the left to flash the ball across the face of goal.
Lorenzo Colombo had the ball in the net, but had strayed offside after a defensive error. Lorenzo Montipò made a desperate reaction save on Samuele Birindelli’s diving header and Andrea Colpani clumsily failed to turn in the rebound.
Colpani again failed to find the target after good work to shake off defenders, while Andrea Carboni made a decisive interception to prevent the Michael Folorunsho tap-in.
Alessio Zerbin was not expecting the goalkeeper to flap at a cross from the right and tried to cushion it towards goal with his chest.
Suat Serdar smashed just over from the edge of the area, but there was a bizarre moment on 68 minutes when the referee pointed to the spot for a penalty. Everyone seemed bemused, as if anything it was Zerbin who jumped at Ondrej Duda during a clearance, so inevitably the referee changed his mind after the VAR on-field review.
Andrea Carboni fired over from a corner, but both teams looked toothless.
Monza 0-0 Verona
