Meiga is the second Nittany Lion receiver to enter the portal after KeAndre Lambert-Smith entered Monday.
After one season at Pitt, Veilleux entered the portal for the second time in his collegiate career.
"We've got to take the next step and I saw them take the next step this spring."
Does KeAndre Lambert-Smith's portal entrance matter? How did AJ Harris perform?
Lambert-Smith was absent from the Nittany Lions' Blue-White Game despite being listed on the roster.
The shirt went on sale on Sunday, April 14.
