Juventus midfielder Mohamed Sissoko has suffered a fresh setback after picking up a hamstring problem against Sampdoria.
Sissoko has only recently returned to first-team action after seven months on the sidelines with a fractured foot, but has now been ruled out for another three weeks.
The former Liverpool man was replaced during the early stages of the second half in Juve's 5-1 win over Sampdoria on Wednesday and is disappointed to be sidelined again.
"I am feeling my hamstring, there is a lot of pain there," said Sissoko.
"It is a disappointment for me when I was getting my match fitness back, starting to feel good and getting to my top form.
"It is a big blow for me. I really need a bit of fortune with my injuries this season.
"Hopefully I will do my best to come back strong."
