Leicester City won't play on-loan Everton striker James Vaughan if injured.
Vaughan joined the Championship side on loan earlier this month and played half an hour of his first game as a Leicester player in their 1-0 win over Cardiff but hasn't featured for the Foxes since.
"James has had a bit of an illness with a stomach upset and he has had other things, and he hasn't been quite ready," said Leicester assistant boss Craig Shakespeare.
"We don't want to ask him to do anything he is not capable of yet. He is one we will have to monitor before every game.
"He is desperate to have an influence and be part of Leicester, and be part of what we are trying to achieve.
"He is getting very frustrated but we have to try to keep his head up. He wants to do well, but we have to manage him."
