Aston Villa boss Steven Gerrard admits he's worried about Boubacar Kamara's injury.
Kamara was forced off late in the first half of Friday's 1-0 win over Southampton and Gerrard admitted some concern at the issue.
The France international was a key summer signing for Gerrard when he joined as a free agent from Marseille.
Villa have already lost £26million buy Diego Carlos for a large chunk of the season with a ruptured Achilles.
Gerrard said: “I'm worried about it. It seems every time we get a win it comes at a cost. I am worried."
