With the off-field future of their coach Mark Hammett unclear, Cardiff Blues fell to a heavy defeat away in Italy as Treviso won 40-24.
Both teams suffered from some awful defence in a chaotic first half but the home team went into the dressing room on top at half-time.
Matthew Luamanu got the first try of the match followed by another from Angelo Esposito and a third from Enrico Bacchin.
Cardiff replied through Lloyd Williams and Josh Navidi to put the visitors back in the game but Jayden Hayward capped of a phenomenal first half performance with a try to finish the half at 27-17.
In a relatively quite second half Henry Seniloli crossed over after just a minute gone. Adam Thomas replied seven minutes later to put the visitors one try away from a bonus point but Hayward who scored half of Treviso's points sealed the win with a penalty just before the end.
Perhaps the news of Hammett's departure had rocked a Blues team in turmoil as the Welsh side struggled to get back to winning ways.
Marco Barbini managed to set up Luamanu who crossed over for the first try of the match after just four minutes. Hayward knocked the conversion attempt just left of the posts but made up for it six minutes later with a penalty.
Enrico Bacchin launched a beautiful pass out to Esposito who ran straight through a gap in the Cardiff defence and past the try line to get another for the Italians.
Rhys Patchell got his team on the score sheet with a penalty before a clearance kick ricocheted off the Treviso pack only to end up in the hands of Lloyd Williams who powered over for a try. Patchell converted to get the visitors to within five.
Swift hands from the Treviso backline left Bacchin with some space on the wing and after a lengthy look upstairs the home team were awarded the try.
The Blues made it a five point game again when a bit of magic from Patchell ended in a Navidi try, Patchell comfortably notched the conversion.
Sam Christie found Hayward on the wing who skipped through the Blues defence to score the last try of the first half but failed to convert with the scores locked at 27-17.
The Italians picked up where they left off after half time when slick Treviso hands resulted in Seniloli scoring one minute after half time, Hayward dissected the posts to make it 34-17.
Hayward got more points to his name by knocking over another penalty to put the home side a further three in front. Adam Thomas crossed over to give the Blues a glimmer of hope after 48 minutes.
Patchell converted to make it a game again at 37-24 The Blues pushed for a bonus point but Hayward put the final nail in the coffin from the kicking tee three minutes from time.
