Adam Idah and Jason Knight have emerged as doubts for the Republic of Ireland's World Cup qualifier against Azerbaijan tomorrow.
Both players are suffering from fever since their arrival in Baku, but they've returned negative tests for COVID-19.
Manager Stephen Kenny says he's not sure if either of them will be able to train later today but confirmed that Idah is further along in his recovery than Knight.
"Adam and Jason both came down with a fever and strong temperature. They passed all the tests, they received negative tests from their antigen tests and PCR tests," the Ireland boss revealed.
"They are all fine, it's just probably from the travel. Adam has a high temperature and is confined to his room. Jason, who is as tough as anything, just has a very high temperature and is unwell.
"We have to see if they are well enough to train today. They were not well enough to train.
"They are still confined to their rooms at the moment and Adam is maybe further down the line than Jason. It came on Jason yesterday before training so he's a bit later.
"We will have to see. The match is not until tomorrow although you do have to name the squad tonight. It's probably an old-fashioned travel thing."
