Atalanta 1 1 Juventus
Juventus are held to a surprise draw, but the worst news comes from Alessandro Del Piero as he limped off with a sprained ankle.
Atalanta were coming off two consecutive victories when they welcomed title holders Juventus to the Stadio Azzurri d'Italia.
Pavel Nedved was ruled out with a throat infection, so Marco Di Vaio pushed Alessandro Del Piero into a deeper role.
Juve maintained some early possession, but the home side had the best chances with Fabio Rossini's drive over the bar and a splendid Lilian Thuram tackle stopping Alex Pinardi in his tracks.
Di Vaio went close on the half-hour mark with a curling left-foot effort from the edge of the box.
However, Atalanta stayed solid and took full advantage of a defensive error just before the break. Thuram kept Alex Pinardi onside and the teenager kept his cool to curl past Gianluigi Buffon with the outside of his right foot.
Juventus drew level at the dawn of the second half when Di Vaio was left unmarked for a free header on a Mauro Camoranesi corner kick.
The Argentine was being watched by Italy boss Giovanni Trapattoni in the stands and only a desperate Massimo Taibi save prevented Camoranesi from scoring.
David Trezeguet did not have a particularly good game and his weak header was well saved, while Paolo Montero's header was also blocked.
Juve continued to push, but nine minutes from time Fabio Rossini saw a goal disallowed for a push.
The tension rose and Cristiano Doni saw his second yellow card for a late challenge on Montero.
The Bianconeri poured forward in the final minutes and Taibi performed another stunning save on Marcelo Zalayeta's shot from eight yards. Del Piero hurt his ankle during that move and limped off, leaving both teams in ten men.
Moments later Luciano Zauri drilled a dangerous effort inches wide of the far post.
