The Montreal Impact will be without midfielder Ignacio Piatti for the foreseeable future. 

It's expected that he will be out for 2-3 months with a knee injury. 

The 34-year-old was removed from Montreal's game on Friday May 24 after stretching out the outer ligament on his right knee. 

Piatti was injured in just his second game back from a different injury that kept him out for 10 games. 

The midfielder has three goals in five games this season.
