Leicester City manager Brendan Rodgers provided an update on James Maddison and Caglar Soyuncu after they were both withdrawn during Thursday's 4-1 win over Randers.
The Foxes grabbed a commanding lead in their Europa Conference League round of 16 tie.
Maddison was withdrawn through illness while Soyuncu suffered a knee injury.
"I've spoken to him and he felt a bit funny in the game, so we didn't want to take any risks with that. We just took him off and he went to see the doctors," Rodgers said.
"He just felt unwell, so we took him off. It's something they will do (checking his pulse). He was sat up (when Rodgers spoke to him). He felt a little bit faint but he was okay."
"Cags hurt his knee. So we will see how that is tomorrow."
