Crystal Palace boss Roy Hodgson confirmed an injury for James McCarthy in victory at Brighton.
Hodgson has revealed why he substituted McCarthy for Jairo Riedewald at half-time against Brighton & Hove Albion today, explaining that the midfielder had collected a slight injury in the opening 45.
Hodgson said: "It's injury unfortunately, he was feeling his hamstring. He was tempted I think to go and give it another five or 10 minutes to see how it goes but the doc, Zaf, Ray [Lewington] and myself made a decision between us that it wasn't worth taking that chance - not when we had fully fit players on the bench like Jairo.
"Unfortunately, Luka, really, although he managed to take his place on the bench, wasn't - we think - really fit enough to play 45 minutes in a match of this type: heavy pitch, very intensive. So I think we made the right decision there putting Jairo on, who of course hasn't been suffering for the last two weeks like Luka with this virus infection."
