Leicester City's Jamie Vardy, Kiernan Dewsbury-Hall and Ricardo Pereira are all doubts for Saturday's crucial Championship match against West Brom.
Foxes leading scorer Vardy took a knock during the week and all three players will be assessed before kick-off.
Defender Pereira is also injured, while midfielder Dewsbury-Hall has struggled with illness this week.
"There is still 24 hours, so will see if we can have some of them back," said Leicester boss Enzo Maresca.
When asked about how costly having the trio out could be, the Italian added: "It is very significant."
Ex-England striker Vardy, 37, has scored 16 goals in all competitions in a season that has been interrupted by injury.
