AC Milan have lost striker Robinho for a month with a leg injury.
With fellow forward Alexandre Pato also sidelined with a muscle injury, boss Massimiliano Allegri could have done without losing the Brazil international as well.
But a statement on the club's official website today read that the former Manchester City man had a "first degree strain to the right thigh during Sunday's Milan-Sampdoria match."
It added: "The recovery time is expected to be three to four weeks, save for complications."
With Zlatan Ibrahimovic having left the club in the summer, AC are low on numbers up front and will now be all the more eager to push through a deal for Roma's Bojan Krkic.
