Southampton striker Shane Long has been ruled out for six weeks after suffering a punctured lung in Saturday's 3-2 defeat to Crystal Palace in the FA Cup.
The Irishman sustained the injury, along with two broken ribs, in a collision with Palace defender Joel Ward at St Mary's.
Saints boss Ronald Koeman could now dip into the transfer market as Long's absence leaves him with just one fit striker - Graziano Pelle.
Koeman's side sit third in the Premier League table as the South Coast club look to qualify for the Champions League.
The transfer window closes on February 2.
