AC Milan have been dealt a blow to their pre-season preparations after Alexandre Pato suffered another injury setback.
On the same day Milan announced the capture of Giampaolo Pazzini - signed from neighbours Inter in exchange for Antonio Cassano and €7 million - Pato sustained a suspected strained adductor during training on Wednesday.
The Brazilian, 22, will now require a scan that will be taken in the coming days in order to assess the extent of the injury.
A club statement read: "AC Milan announces that during a game held in today's workout, Alexandre Pato has reported a problem with his left adductor. In the coming days further medical examinations will be made to determine the extent of the damage."
Pato has now suffered as many as 16 separate injuries since arriving at San Siro in January 2008, limiting him to 113 appearances in Serie A.
With Zlatan Ibrahimovic now at Paris Saint-Germain it had been hoped Pato could become the club's main striker and add to his phenomenal strike rate of 0.45 goals per game.
