The 25-year-old Lampre-Merida rider crashed due to a hole in the road whilst cycling in the town just south of Parma, Italy.
Malori expressed his frustration at the turn of events but conceded he was fortunate not to suffer a more serious injury.
“It’s a pity I must stop for some days because of this accident,” Malori explained.
“Luckily, it’s nothing too serious, but I feel pain because of a hematoma. I must rest for some days, then I hope to be back on the bike again soon.
“I’ll keep in contact with the team medical staff and I’ll undergo tecarterapia (an electromedial therapy).
“I’d really like to return as soon as possible, in order to avoid losing all the progress we made in Mallorca with the Merida technician concerning the time trial positioning.”
Malori was the 2011 Italian time trial champion and was 10th in last year's world road race.
