Marc Guehi is eligibile to play for Manchester City in the FA Cup despite already playing in the competition this season for Crystal Palace during their shock defeat by non-league side Macclesfield.
The England centre-back, who captained Palace in last season's final victory, has been given a second chance at glory and can feature against League Two side Salford City following a refresh to the rules before the 2025-26 season.
Under the old rules Guehi would have been cup-tied, but the Football Association now deem that "a player may play for a maximum of one other club in the competition proper", but cannot play for two different teams in the same round.
It is the second time that Pep Guardiola's side have benefitted from the changes after Antoine Semenyo played in both legs of the EFL Cup semi-final against Newcastle United following his £65m move from Bournemouth, when he previously would have been cup-tied.
City are not the only beneficiaries, with Leeds now able to field Facundo Buonanotte after he completed a loan move from Brighton.
The Argentine, who was loaned to Chelsea during the first half of the season, started in the Blues' FA Cup third-round victory against Charlton Athletic.
Chelsea themselves will be able to call upon January recruit Yisa Alao, who featured for previous club Sheffield Wednesday in their FA Cup defeat against Brentford.
