Leeds United's next Premier League opponents Aston Villa have been dealt a potentially significant blow after midfielder Boubacar Kamara limped off in their 1-0 win over Southampton.
Kamara joined Villa this summer on a free transfer from Marseille and has played in every single one of their games so far this season.
The French international has been marshalling Steven Gerrard's midfield this season operating in the heart of their engine room.
