The Czech rider crashed on his way to his Soudal Quick-Step team bus after signing the start sheet.
"There are 100 rules (to be respected) for the team but someone with a backpack knocked Jan Hirt down on his way from the signatures to the bus. Three broken teeth," team boss Patrick Lefevere wrote on X.
The first stage is a 206-km ride from Florence to Rimini.
