West Ham youngster has signed on loan with Mansfield.
Afolayan's move was confirmed by Mansfield's official website, billing the prospect as an 'exciting striker'.
The loan deal runs until January, and Mansfield said they beat off competition from clubs to sign him.
Afolayan sent a message on Twitter expressing his happiness at getting the chance.
Afolayan, 21, is at a stage where he needs to play competitive football.
He signed for West Ham from Solihull Moors in January 2018, and had previously been in Chelsea's academy.
Former West Ham full-back Paul Konchesky sent Afolayan a message of support.

League Two Mansfield Town have had a tough start to the season, winning only one of their opening five league games.
Afolayan has the chance to become a hero if he can help the Stags turn their results around.
