Wes Morgan has been ruled out of Leicester's trip to Arsenal with a hamstring injury.
The defender limped off in last week's 1-1 Champions League quarter-final draw with Atletico Madrid, which saw the Foxes exit the competition 2-1 on aggregate.
Boss Craig Shakespeare had hoped it was cramp but he will now be without the centre-back for Wednesday's clash at the Emirates Stadium.
He said: "Unfortunately Wes won't make it. He has just overstretched his hamstring. It hasn't gone into a full blown pull but we have to be mindful. So as a precaution he is out then we will look towards Saturday.
