The Dutchman will be missing for as much as two months after injuring himself trying to save Carlos Tevez's strike during the Swans' narrow defeat to Manchester City on Saturday.
The Dutchman had to be stretchered off the field against Manchester City on Saturday after injuring himself in the unsuccessful act of diving to save the 25-yard Carlos Tevez strike that was decisive in the 1-0 City victory. Gerhard Tremmel, the 33-year-old German who replaced Vorm at the Etihad, is expected to step into the starting role while Vorm recovers.
“Michel has a partial rupture of his adductor muscle. He are looking at six to eight weeks out," Swansea medic Kate Rees said.
The injury means Vorm could miss games against Liverpool, Chelsea, Arsenal, Tottenham and Manchester United.
