Wales have called Ospreys wing Eli Walker into their World Cup squad as a replacement for the injured Liam Williams, the Welsh Rugby Union has announced.
Scarlets back Williams suffered a foot injury during Wales' 15-6 defeat against Australia in last Saturday's Pool A decider at Twickenham.
Walker will link up with the squad immediately at their Surrey base ahead of this weekend's quarter-final appointment with two-time world champions South Africa.
A statement from the WRU on Tuesday morning confirmed: "Ospreys wing Eli Walker has been called into Wales' Rugby World Cup squad and will link up with the squad immediately.
"The 23-year-old was originally named in the 31-man RWC squad but was released due to injury ahead of the tournament.
"Walker replaces Liam Williams, who was released on Sunday."
