Chelsea defender John Terry is struggling to be fit for England's Euros opener against France.
Terry has yet to return to full training.
Hodgson put his team through their paces before flying from Luton, but the Chelsea defender, who pulled his hamstring against Belgium, again failed to take part.
England will train at their Krakow training base this morning and Hodgson's medical staff will make a late decision on whether Terry can play a full part.
