Ireland prop Tom Court has been called up by the British and Irish Lions as injury cover for Alex Corbisiero, who has a calf issue.
Brisbane-born Court was in Australia and goes straight onto the bench for the side to play the Melbourne Rebels on Tuesday.
Corbisiero impressed in the first Test, but was eventually replaced by Mako Vunipola in the second half after receiving treatment earlier on his calf.
With the London Irish prop's availability for the second Test now in doubt, Vunipola has been withdrawn from the midweek side to face the Rebels.
The other major injury concern for the Lions is Paul O'Connell. The former captain has reportedly broken his arm, but continues to be assessed and has not yet been ruled out of the remainder of the tour.
England lock Geoff Parling was the second row replacement during the first Test so would seem likely to fill in if O'Connell is ruled out, but Parling remains set to start and captain the Lions against the Rebels.
