Taylor showed he was on the mend by scoring a brace in the victory against Stoke on Saturday, which all but secured the club's top flight status.
It was little wonder he celebrated after complaining of feeling unwell following the Blackburn match in February.
Coyle said: "Matt felt ill and we had him tested after the match. It showed he had glandular fever at some point although they can't pinpoint exactly when.
"We all recognise the qualities of Matt Taylor. He showed that last week and I am delighted for him.
"He works ever so hard every day in training. I always feel when players work as hard as that they get their rewards."
