Was it even just read after the Second Reading and before the Alleluia?
We are now in the Octave of Pentecost that was unfortunately lost in the Ordinary Form (OF). An "Octave" is the eight day period following a major feast, a prolongation of that feast. In the traditional, there are three, Christmas, Easter and Pentecost and of course in the OF, only Christmas and Easter. Prior to 1962 there were more including Epiphany. Others included Corpus Christi, Sacred Heart, Sts. Peter and Paul and more of lower rank.
There is this little story from Father Z. It seems that he was told this story by an elderly, retired Papal Ceremoniere or a Master of Ceremonies who (according to him) was present at the event about to be recounted.
The Monday after Pentecost in 1970 His Holiness Pope Paul VI rose bright and early and went to the chapel for Holy Mass. Instead of the red he expected, there were green vestments laid out for him.
He queried the MC assigned that day, "What on earth are these for? This is the Octave of Pentecost! Where are the red vestments?"

"Green? That cannot be!", said the Pope, "Who did that?"
"Holiness, you did."
And Paul VI wept.
And the rest of us have been weeping ever since.
And then there is the Vigil...
