Aston Villa have striker John Carew, winger Ashley Young and defender Curtis Davies undergoing treatment in the build-up to Sunday's clash against West Brom.
All three players missed Villa's 3-1 win against Litex Lovech in yesterday's UEFA Cup tie in Bulgaria.
Carew (ankle) and Young (knee) were both injured at Tottenham on Monday.
Davies was a late withdrawal against Litex when he woke up on the morning of the game with a slightly swollen knee.
