FIFA will propose allowing teams to use a fourth substitute in extra time when the International FA board meets next month.
The rules-making panel is set to decide at a meeting in England on 3 March if increasing the current quota of three replacements would help improve matches and reduce injuries.
A Fifa statement said: "The Fifa Task Force Football 2014, the medical committee and the football committee support the proposal in order to maintain the technical level until the 120th minute and to protect the health of the players."
