Blackpool are anxiously waiting to find out the full extent of defender Alex Baptiste's hamstring injury.
The 25-year-old lasted just 34 minutes of the Seasiders' 2-0 defeat at Leicester City on Tuesday.
"It looks like fatigue because I'm asking the same people to do it over the last four or five games.
"He's one of the fittest lads we've got but that's how difficult this league is," manager Ian Holloway told BBC Radio Lancashire.
Holloway added: "People say 'why are they tired?' - that's all they do all week. But it's not that.
"It's the level that you've got to be at to play as well as we have done over the last few weeks. Sometimes that's hard to keep emulating.
"Maybe I should have changed the team."
