Montreal Impact have signed Portland Timbers goalkeeper Troy Perkins.

Perkins moves to the Impact in a trade for Donovan Ricketts.

"We would like to thank Donovan for his services with the Impact, but we did not feel he fit into our plans moving forward," Impact sporting director Nick De Santis said in a statement Tuesday.

"We are happy to be able to add Troy to our group and we think he will make an immediate impact in what we are trying to achieve," Impact head coach Jesse Marsch said. "We feel this will help us make a strong push at the end of this year, as well as solidify ourselves for the future."
