Daniel Farke delivered two new injury concerns in his pre-Luton press conference on Friday afternoon.
Xavi Quintilla is expected to miss out after picking up some problems in the last pre-season friendly against SV Darmstadt.
Onel Hernandez is also a doubt, Daniel Farke explained: "There's a question mark on Onel Hernandez as well. If his body is able to handle training this afternoon he could travel, but won't start.
"We also have our long-term injuries to Sam Byram and Grant Hanley."
