( dpa ) - Juventus were stunned 2-1 Saturday at struggling Reggina, missing a chance to leapfrog second-place Roma in the Italian Serie A.
Juve's game in Reggio Calabria was a far cry from the gritty showing that allowed them to beat Roma the previous weekend.
Roma remained second on 48 points, one above Juventus, but 11 adrift of leaders Inter Milan.
Reggina closed a four-defeat run but remain third-from-last in the relegation zone.
The absences of strikers David Trezeguet and Vincenzo Iaquinta weakened Juve's striking power, allowing the hosts to run minor risks in a first half that they closed with a one-goal lead.
Striker Franco Brienza connected on 32 minutes with a shot from Bruno Cirillo and fired past a helpless Emanuele Berardi, who filled in for Gianluigi Buffon as the international struggles with nagging back pain.
Juve's only chance in the first half was a glaring blunder by Mohamed Sissoko, who on 27 minutes fired high before the gaping goal.
Czech veteran Pavel Nedved opened Juve's hammering attacks in the second-half, firing narrowly wide on 51 minutes before Mauro Camoranesi twice shot above the bar.
Nedved adjusted his aim on 66 minutes with a fast but central shot well deflected by Andrea Campagnolo, who five minutes later bore much responsibility on a drive from captain Alessandro Del Piero.
On 80 minutes, Cristiano Zanetti came close to reversing the score for Juve with a dangerous drive but again fell behind in injury time as Nicola Amoruso, former Juventus striker, converted a spot kick.
Juve complained bitterly to the referee after having at least three penalties denied.
In an earlier weekend opener, struggling Torino and Parma played out a spectacular 4-4 draw.
Roma take on fourth-place Fiorentina for a top-billing match Sunday, when Milan are at mid-table Sampdoria.
