The three have each represented England before, with Rodney being the most recent debutant after an international call-up in November 2021.
Wells-Morrison also began his England youth career last year, and Whitworth has represented the Young Lions for several years.
Rodney spent most of 2021/22 helping Rob Quinn's Under-18s finish third and signed his first professional contract in October. Wells-Morrison and Whitworth mostly played with the Under-23s.
They link-up with England for three games in a tournament in Zagreb.
