Duncan's #EVEAVL verdict:
One of those objects hit Cash and Digne, the latter of whom spent three and a half years with Everton before joining Villa last week after falling out with former boss Rafael Benitez.
Both players fell to the turf and held their heads, but they were able to continue.
Everton confirmed shortly after the 1-0 loss it they had identified the supporter and the matter is now being dealt with by Merseyside Police.
"Police have arrested a supporter at Goodison Park for throwing a missile onto the pitch during today's Premier League match against Aston Villa," a club statement read.
