Melbourne City's keeper conundrum
Velaphi was injured in a collision with Perth Glory's Guyon Fernandez in their FFA Cup semi-final loss on Wednesday.
Thomas Sorensen, who is the club's first-choice goalkeeper, was forced to come on for the remainder of the game.
With Velaphi ruled out of Sunday's home tie with Central Coast Mariners, in a cruel blow for City their third and fourth-choice goalkeepers Yaren Sozer and Jack West-Astuti are also unavailable.
The club elected to sign Alex Pavlidis, who helped guide Pascoe Vale to the semi-finals of this season's NPL Victoria competition.
Pavlidis, who also works in City's media department, was playing for Box Hill United in the second-tier of Victorian football just two seasons ago, where he was awarded the NPL1 goalkeeper of the season.
He was picked up by Pascoe Vale at the start of the 2015 season and established himself as one of the best goalkeepers in Victoria.
The goalkeeper was also part of the City squad that played Adelaide United in a pre-season clash in Darwin.
Pavlidis will sit on the bench against the Mariners at AAMI Park on Sunday.
