Liverpool defender Philipp Degen is facing a frustrating spell on the sidelines after breaking two ribs.
The Switzerland international picked up the knock while on Carling Cup duty against Crewe on Tuesday.
Degen had to be replaced by Jamie Carragher after 73 minutes and appeared to be in some discomfort after suffering the blow in an innocuous looking challenge.
The news comes as a major setback to the 25-year-old as he looks to establish himself at Anfield following his summer arrival at the club.
"He has broken two ribs," Reds boss Rafa Benitez told the club's official website.
"He is very unlucky."
