The Ghana international, who has been suspended indefinitely at Schalke will not be joining the Portuguese side after a deal broke down
The Ghana international was suspended indefinitely by his club, alongside Sidney Sam, following a Bundesliga defeat to Koln in May.
Sam has since been welcomed back into the squad, but Boateng looked certain to join the 18-time Portuguese champions following negotiations this week.
However, Sporting confirmed on Wednesday that talks had fallen through due to failing to agree personal terms.
“Sporting Clube de Portugal, Futebol, SAD, announces that, after negotiations with Kevin-Prince Boateng, it was not possible to agree on his image rights,” read a statement.
“Sporting SAD wishes Boateng both personal and professional happiness.”
