Juventus have confirmed that Amauri will be out of action for much of March with a thigh injury.
The 29-year-old striker lasted just 14 minutes of Juve's 0-0 draw with Ajax on Thursday, which saw them prolong their Europa League adventure.
He now appears set to sit out both legs of a last-16 tie with Fulham, while also missing crucial domestic fixtures.
"Amauri underwent tests following the injury suffered during the match against Ajax," read a statement on Juventus' official website.
"The tests confirmed the diagnosis made after the match. The prognosis is of 25 days."
Amauri joins Gianluigi Buffon on the sidelines at Stadio Olimpico, with the talismanic keeper set to be out of action for a month with a thigh problem of his own.
