Juventus ace Andrea Pirlo is out of their Champions League tie with Borussia Dortmund.

Juve go to BVB this week defending a 2-1 first-leg lead.

"Today Andrea Pirlo underwent some medical examinations," the club confirmed on its official website.

"The ultrasound check showed good progression in the healing of the injury, but not enough for him to be available for the trip to Dortmund.

"The midfielder will therefore continue on his personalised rehabilitation programme."
